Codec problem in Ubuntu 24.10

[conualfy]

Hi there! I have switched to the latest Ubuntu some time ago and only yesterday I needed to make a recording. My surprise was that although the program starts fine, when pressing Record, it cannot do any recording. I am copy-pasting the visible log, I do not know exactly how to fix this. It is most likely some encoding problem. My laptop is dual GPU and I am using the integrated Intel GPU (+ Power mode: balanced), as I want more battery life, I don't need more graphical performance and I want no noise while using the laptop.

I can provide any other log needed if the commands are posted here. Thank you very much.
