OBS can only record at 6FPS and while running slows everything to a crawl

This is not a hardware issue, my specs are Ryzen 5, 1600 with rx 480 gpu, I used to be able to record just fine, now it can only record at < 6 fps and lags the entire system down. htop doesn't show anything interesting. I tried with the current latest version(28.0.3) and 27.0 but no luck. Is there any logs or something I can look into?

Include a log file if you have a problem: Here's how.

To upload a log file, go to the Help menu -> Log Files -> Upload current/last log file. The current log file is for the currently active running session. The last log file is for the last time you ran the program. We recommend always including it if you have a problem just in case.
