The latest aap-lv2 seems to cause invalid pthread_join() under certain (but unknown) condition:

2022-02-16 17:43:48.418 7257-7270/? A/libc: invalid pthread_t 0xbebebebe passed to pthread_join

When I enabled ASan (well, TSan) in aap-mda-lv2, I get this log:

The same kind of crash seems to happen to aap-fluidsynth too.
