After roughly 1h40 minutes of streaming, OBS stops recognizing audio I/O / soft-locks

Hi folks,

I am on Ubuntu 22.04.2 LTS and using the Flatpak for OBS 29.0.2.
My system is configured to use pulseaudio.

After roughly 1h40 (can be 1h38, 1h49), sound stops coming through OBS (all the meters go dead), and the fastest way I've found to "fix" it is to hit the X to close out of OBS. I get the warning that it'll stop streams, I say OK. After a few seconds, I see the pop-up that OBS stopped responding, and do I want to force quit; I do, then I start OBS again, and everything eems to be fine.
Sending the logs over for analysis after the loss of sound, either before the force quit or after the force quit (i.e. current or previous logs) does not reveal anything amiss in the analysis tool, and nothing in the logs look like anything noteworthy.

I have wiped the profile and settings for OBS and started from scratch, and that did not make the problem go away.
I unfortunately did not track exactly what changed, but the setup used to work for longer. Among the two most significant external changes that happened:

1. I got a faster internet provider so I moved my upload bitrate limit from 2000 kbps to 6000 kbps
2. I changed the RAM in my computer (from 16GB to 64GB)

Nothing else seems particularly impacted by the RAM change, though that does not necessarily mean anything.

Other streaming / audio settings:
- audio bitrate 160
- encoder - software, x264
- encoder preset - veryfast (default)
- Twitch VOD track (track 2)

I'm not particularly fluent in the details of Linux audio, so I am likely missing critical information, if so, I'm sorry, please let me know what else I can do to bring you more information on this.
