Firefox won’t launch after running selenium tests

Bit of a niche question hope someone can help.

I’m running some website testing and have a script set up to open Firefox at regular intervals using Selenium in python, run tests and exit. Running it in a MacBook using Catalina and have the latest versions of Firefox. I tried a different MacBook as well.

Randomly, after running enough tests, it will fail to launch, throwing and error code “can’t quit and exited process”.

Once this happens, I can’t open Firefox at all, even manually. The icon just bounces and fails to launch. Oddly enough, I can’t launch Chrome either, even if I haven’t launched it since restart. Restarting my computer will fix the problem always.

I’ve tried running in headless mode to, no avail. Any ideas here?
