Is that on any class of machine running 6.9? It doesn't look related but did you take a look at the other RV related posts here?
Not a dev but looks like another Pulse related issue, looks like its wanting to do some context switch or apply a lock in kernel space but the device isn't responding. Someone here will point out where I'm wrong hopefully.

Hi all,

I have an issue with RV. It keeps crashing all the time when I am playing clips with sound. It happens with our clips and also with videos downloaded from the internet.

does anybody has this problem?

It crashes with:

Segmentation fault

and

Assertion 'pa_atomic_load(&(c)->_ref) >= 1' failed at pulse/context.c:1032, function pa_context_get_state(). Aborting.
Assertion 'pthread_mutex_destroy(&m->mutex) == 0' failed at pulsecore/mutex-posix.c:83, function pa_mutex_free(). Aborting.
Dump path: /tmp/0c934936-29db-57ad-6200ab3a-42764f56.dmp
Aborted

and sometimes it just keep hanging. Output from strace the process:
