[Bug] ImHex Crashes Immediately After Opening a File

[Mootix1313]

I originally put these details in the comment section of issue #1485. As suggested, I installed the nightly version (build #5202) to see if my issue would be alleviated. However, it still persists. I've updated the ImHex details section, and included a link to the most recent crash report.

How can the issue be reproduced?

Steps

1. Start-up imHex.
2. Select a file to open in imHex.

Details

After attempting to open a file, imHex immediately crashes, which is followed by the Problem Report for... window.

Here, you're given the choice to acknowledge the issue by selecting OK (this closes the session/window), or to try to reopen the program by selecting reopen. imHex reopens just fine. However, if I opt to restore my lost data by selecting Yes, Restore imHex will attempt to do so, but will immediately crash. Sometimes I'll get a very short glimpse of the file I'm trying to open.

Side note, the files I'm trying to open are local to my computer.

Did some further investigation now and it looks like this is a libmagic bug: https://bugs.astron.com/view.php?id=125
I was able to reproduce the crash now on my Mac but it doesn't happen on Windows as far as I can tell.

I've disabled compression support for now for libmagic and that seems to have fixed it for me. Could you please check the latest nightly again if it's still happening for you there?

I've tried build #5205 and #5210, which both produce the same behavior. This also occurs when selecting Create New File from the main landing page after opening ImHex.

Just an update, the current native arm build (v1.33.0) exhibits the same behavior described above. However the x86_64 version, imhex-1.33.0-macOS-x86_64.dmg, operates just fine. I wasn't able to run the x86_64 version of the previous release, however.
