Official Fedora LMMS package killed by SIGSEV on "Preparing UI" screen

Nobody has claimed this yet.

### System Information

Fedora 39 (6.8.9-200.fc39.x86_64), i3wm

### LMMS Version(s)

1.2.2

### Most Recent Working Version

_No response_

### Bug Summary

I just installed LMMS through dnf and then launched it through dmenu after it was finished. The app displays the "Preparing UI" popup for a second, but then it immediately crashes.
If I try running it through the console, I get the following output:
```
Notice: could not set realtime priority.
VST sync support disabled in your configuration
Cannot load library /usr/lib64/lmms/libcarlabase.so: (libcarla_native-plugin.so: cannot open shared object file: No such file or directory)
Cannot load library /usr/lib64/lmms/libcarlapatchbay.so: (libcarlabase.so: cannot open shared object file: No such file or directory)
Cannot load library /usr/lib64/lmms/libcarlarack.so: (libcarlabase.so: cannot open shared object file: No such file or directory)
Segmentation fault (core dumped)
```
I installed lv2-carla through DNF, but then I got the following output:
```
Notice: could not set realtime priority.
VST sync support disabled in your configuration
Segmentation fault (core dumped)
```
Uninstalling lmms and reinstalling it via the official AppImage file from the website seems to have fixed the issue.

### Expected Behaviour

LMMS should launch normally.

### Steps To Reproduce

Install lmms and lv2-carla using dnf on Fedora 39 (`sudo dnf install lmms lv2-carla`) then try launching the application.

### Logs

_No response_

### Screenshots / Minimum Reproducible Project

I think these two files were too long to include in the Logs section of this issue so I'm attaching them here.

### Please search the issue tracker for existing bug reports before submitting your own.

- [X] I have searched all existing issues and confirmed that this is not a duplicate.

Reproduce the crash with `sudo dnf install lmms lv2-carla` on Fedora 39 and review the reported missing Carla libraries. Start with the attached `backtrace.txt` and `core_backtrace.txt`; done means the Fedora package launches normally past the “Preparing UI” screen without a segmentation fault.
