OBS will not launch

[86ul]

Hello,

Today I installed OBS on a up tot date Mint 20. After first use, I can not launch OBS any more. Even going back with TimeShift 'to yesterday' and reinstalling, it will not launch anymore. After creating run_obs_studio.sh with only LIBGL_ALWAYS_SOFTWARE=1 as text and running it in terminal, I get some result (see attachment).

As a post W10-64 M20 newbie, the only error that I can spot in that is:

info: NV12 texture support not available
info: Audio monitoring device:
name: Default
id: default
info: ---------------------------------
warning: Failed to load 'en-US' text for module: 'decklink-ouput-ui.so'

(...)

error: os_dlopen(../obs-plugins/obs-browser->../obs-plugins/obs-browser.so): ../obs-plugins/obs-browser.so: cannot open shared object file: No such file or directory

Hopefully you can work it out.
