OBS is using ~35% of CPU after 10 min, resulting in audio problems and crash

[Boernstain]

Hello,
when I start OBS, the CPU and GPU utilization values are completely within limits. About 6% CPU utilization without stream, about 11% with stream. But after about 10 minutes of streaming, the CPU utilization goes up to 35% and sometimes 40%. Which is really weird, since I'm coding over the GPU.
I get sound problems in individual sources (it sounds stuttery, like the sound can't be processed fast enough) and after a few more minutes OBS sometimes crashes.

I only got this problem with OBS 28, before that it never happened.
Yes, I have many scenes that are also nested, with many browser sources. But that hasn't really been a problem so far.
I think have updated all plugins and the log analyzer of OBS gives neither critical messages nor warnings.

Some infos about my setup, the rest is in the log down below.

Small update for all who run into a similar problem: The problem is the plugin "Audio Monitor". According to the developer it is compatible with OBS 28, but apparently not for me. As soon as I move a fader, the high CPU load comes up and OBS crashes. Not without plugin.

I was using the Audio Monitor Plugin from Exeldro
Many people complain that the plugin is probably not compatible with TouchPortal at the moment. I don't have TouchPortal, but use a Streamdeck, so maybe it's somehow related to that.
