Not much info in the log above as there's no encoding session but I have some thoughts:
Your system is thin & it's low on RAM the moment OBS is opened. Close all apps not needed when using OBS. Clean-up your Scene Collection too, plenty of resources can be saved just by eliminating all of those duplicate captures. Heck start a new collection while you're troubleshooting, add just a single Source & test.
