MarsEdit Preview crashes. Setapp?

I'm using the setup versions of MarsEdit and Marked, and I can't get the MarsEdit Preview to work. Often the app crashes (see attached) instantly when I select Preview > MarsEdit Preview. Every once in a while it opens to a blank window, even though I have a MarsEdit Post open. One time I saw an error message saying MarsEdit cannot be found or MarsEdit is not running (I can't get this to show up again).

As an experiment, I downloaded the non-setapp trial of MarsEdit and Marked's preview worked. So there may be an incompatibility with the setapp version of MarsEdit?

As an interim hack, I've been manually using the clipboard preview, but I'd really like to get this working. I have a use case for a custom preprocessor that MarsEdit's built-in preview can't support.

The app works great with other files, just can't get MarsEdit to work reliably. Love the app!

    So I haven't tested the MarsEdit integration for a while. On my machine
    it works with all 3 versions of Marked (MAS, Paddle, and Setapp), but it
    actually works _best_ with the Setapp version. The other two don't seem
    to be automatically updating.

    The only thing I can think of is if the permissions dialog that would
    allow Marked to control MarsEdit was denied and Marked isn't handling it
    well. Do you know if you ever received that dialog?

    My best suggestion would be to delete your preferences and see if a
    clean start helps out. This would be done by:

    To delete your preferences with the direct (non-MAS) version of Marked

    1. Quit Marked
    2. Delete the file at
    ~/Library/Preferences/com.brettterpstra.marked-setapp.plist (and any
    other files starting with com.brettterpstra.marked2). If you're not sure
    how to access this folder, open Finder and press ⌘⇧G, then paste
    "~/Library/Preferences" (without quotes) into the box.
    3. Reboot the computer (this is important as OS X aggressively caches
    preferences and may just restore the deleted file without your
    4. Launch Marked

    Thanks. I deleted the preferences plists and rebooted but no luck.

    99% sure I never received a permission dialog where Marked requested to
    control MarsEdit. In System Preferences, I don't see Marked or MarsEdit
    show up in the Security & Privacy > Privacy > Automation list (and I think
    I can't manually edit that list).

    As a sanity check I removed all the Marked permissions I could (Full Disk
    Access, etc.) and no effect.

    If it helps, attached is a new crash log. I think the main error message is:

    **** Terminating app due to uncaught exception
    'NSInvalidArgumentException', reason: '*** -[__NSCFString
    stringByAppendingString:]: nil argument'terminating with uncaught exception
    of type NSExceptionabort() called*

    This message is different from the original crash report, but I've seen it
    many times before.

    Even if we can't get to the bottom of this, appreciate the help!

    Can I see the contents of the blog post you're trying to preview? Marked
    seems to be trying to extract some contents that seem to exist but are
    returning empty responses, so I need to narrow down what's triggering
    that to begin with.

    It seems to happen for all posts. I just made one containing only a
    paragraph of plain text lorem ipsum (see screenshot) and Marked crashed the
    same way.

    I also have a custom preview template in MarsEdit. I thought Marked may be
    seeing that somehow. But it still crashes even after restoring the default

    Marked should be fully ignoring any custom templates. It attempts to get
    the title, content, extended content, and any tags used. The crash seems
    to be happening when it scans for embedded scripts, of which there
    shouldn't be any in most MarsEdit posts. I have a that attempts to
    catch that error and ignore it, would you be willing to run a test

    If so, download and unzip this version and see if it fixes the issue:

    (this is a Setapp-specific build, should work with your existing
    subscription setup)

    Ok, the test version (running just from ~/Downloads) does not crash but the
    MarsEdit Preview is blank.

    Also, not sure if this is a clue: if I change "process markdown with:
    Discount (GFM)" to "process markdown with MultiMarkdown", the test version
    crashes but with a different message:

    Application Specific Information:
    > *** Terminating app due to uncaught exception
    > 'NSInvalidArgumentException', reason: '*** -[NSRegularExpression
    > enumerateMatchesInString:options:range:usingBlock:]: nil argument'
    > terminating with uncaught exception of type NSException
    > abort() called

    The (non-test) setapp Marked crashes regardless of MMD or GFM.

    Crash log attached.

    Using MMD, does the preview update with actual content if you hit ⌘R?

    Also, when you say blank, do you mean entirely blank, or with a message
    displayed about launching MarsEdit or similar?

    Oh, I should have asked this a while ago, but which version of MarsEdit
    are you using, and is it from the MAS?

    It looks like this thread's died out, but let me just say:

    1) if there is any info I can provide that might help, please let me know!

    2) if we can't figure this out, or you're too busy: *No big deal.* I'm a
    very satisfied Marked user [1]. I'm sure this is some weird edge case,
    likely my fault.

    Love all the stuff you're putting online, keep up the great work!

    Not dead, was waiting to hear what version of MarsEdit you were using.

    Oops, my bad! MarsEdit Version 4.4.2 (9294) Setapp Edition

    Huh. On my machine my copy isn't even picking up the Setapp version
    while it's running. If I hit ⌘E it opens the right version, but it's
    not showing a preview at all. This might be related to what you're
    seeing and will take some more digging on my part. I don't have an
    immediate solution, I'm afraid.
