Hi,
I installed VCV Rack 2 for the first time on linux (Pop!_OS 22.04 LTS) and it keeps crashing at seemingly random times. I tried versions 2.0.6 and 2.1.0 with the same result. Each time I launch it a dialog informs me that the previous session crashed even when I simply opened and closed it normally. It also crashes nearly everytime I try to change the output audio driver. Speaking of audio drivers, the same one will sometimes work and others will just output no sound. The drivers themselves work since I can use them in other programs.
Here is the log for a session that crashed when changing the output driver:
