Most probably one (or more) of the plugins are causing the crash.
You have to check one by one for updates and if they are compatible with OBS 29.1.3
Completely remove any plugin you're not using.
A crash report is needed. If there's no crash report then the issue may be on the GPU driver or the GPU itself.
An streaming or recording (the one you do) test is also needed for the log file to be complete.
OBS (Open Broadcaster Software) is free and open source software for video recording and live streaming. Stream to Twitch, YouTube and many other providers or record your own videos with high quality H264 / AAC encoding.
