Hello,
I did post about this on the OBS forum, but no responses so far.
OBS was working, but now it dies. I launched in a terminal and the launch ended with a segmentation fault and ICE default IO error handler doing an exit()
I found this in journalctl:

In the terminal, OBS reports several errors that seem to be about language/locale. Here are a few examples:
warning: Failed to load 'en-US' text for module: 'decklink-captions.so'
warning: Failed to load 'en-US' text for module: 'decklink-ouput-ui.so'
warning: Failed to load 'en-GB' text for module: 'linux-alsa.so'
warning: Failed to load 'en-GB' text for module: 'linux-capture.so'
libDeckLinkAPI.so: cannot open shared object file: No such file or directory
warning: A DeckLink iterator could not be created. The DeckLink drivers may not be installed
info: No blackmagic support
warning: Failed to load 'en-GB' text for module: 'linux-jack.so'
warning: Failed to load 'en-GB' text for module: 'linux-pulseaudio.so'
I’m guessing the warning are not going to affect functionality; I don’t have a Blackmagic device.
There are errors regarding pulse and v4l2:
error: pulse-input: An error occurred while getting the source info!
error: v4l2-input: Unable to open device
error: v4l2-input: Initialization failed
Any ideas where to start, please?
Thanks.
