Crashes when performing actions such as encrypting and decrypting

[h3mhFs7bjD]

Software version: 2.1.3-qt6 appimage
OS: Fedora 39 in a VM

Randomly, when decrypting the software closes. It does not happen every time, but often enough to be reproducible. I can keep pressing Encrypt or Decrypt and it'll crash after several times, consistently.

Trace/debug around the time it occurs:

I'm currently developing under macOS, a platform that may not be very sensitive to memory issues. Theoretically memory issues are intolerable, so I think it's time to test the normality of memory usage under the Linux platform, although it's a tough job. :)

[saturneric]

After some testing on my part and analyzing it with the ASAN tool, I didn't find any problems with memory overflow. This could also have been fixed by chance with my other previous mods. All memory leaks found have been fixed.

I'm going to close this ISSUE for now and re-open it if you still reproduce the problem in a new version.

Refer: ca3a64b

[h3mhFs7bjD]

The exact same issue persists. I don't use this much, but with 2.1.4 I can reproduce it exactly the same way.
