I apologize if this is a duplicate. Searching the forum didn't turn up any posts with a similar title. I'm using Ubuntu 22.04.1 and my OBS version is 19.0.2.
OBS crashes on startup after briefly showing up for a few seconds and then freezing. Running a gdb backtrace, it returns "Segmentation Fault: error while loading shared libraries: usr/lib/x86_64-linux-gnu/libQt6Core.so.6: cannot open shared object file". So I downloaded and replaced libQt6Core.so.6. Running OBS again, it returned the same error, but this time for libQt6Widget.so.6. Then, I completely reinstalled libQt6 (including libQt6Core, libQt6Widgets, libQt6GUI, etc...). Running OBS again returned the original error in gdb backtrace (libQt6Core).
I then uninstalled and reinstalled OBS with sudo apt-get remove obs-studio and sudo apt-get install obs-studio. OBS no longer opens, freezes, and then crashes. It just doesn't open anymore. This changed the error in gdb backtrace to "Segmentation Fault: error while loading shared libraries: usr/lib/x86_64-linux-gnu/libicui18n.so.69: no such file or directory". I checked the folder and I do have libicui18n.so.70, but not 69. I managed to find an icu69 download (with libicui18n.so.69, libicutest.so.69, libicuuc.so.69, etc...).
The error then changed to:
"Program received signal SIGABRT, Aborted.
__pthread_kull_implementation (no_tid=0, signo=6, threadid=140737101386752) at .nptl/pthread_kill.c:44
44 ./nptl/pthread_kill.c: No such file or directory."
After running (gdb) bt full:

#11 0x0000555555601ded in main ()"
At this point, I genuinely have no idea what the problem even is. I think pthread_kill has something to do with python or C++, but all the stackoverflow posts about the error are for improperly formatted code. I would really rather not do a clean install of OBS if it means I'm going to have to set everything up all over again, but if that's the only plausible solution, I'll do it.
I believe SIGABRT happens (based on what I've found on the internet) because of internal library errors, but I don't know why the program is looking for ./nptl/pthread_kill.c since ./nptl/ isn't and never has been a directory. OBS has been working fine for quite a while for be and this issue suddenly began to happen. The only thing that changed is that I, the day prior to this issue beginning, installed a second hard drive, but I can't see that being the cause of this issue.
Any help is appreciated. Thanks!
