Reinstall amdgpu (or switch to amdgpu-pro)

I’d suggest you focus on repairing possible damage related to your quoted comment, rather than assuming another graphic driver will fix it.

The first thing you could try is to create a new user profile to see whether these crashes may be only limited to your current profile.

Additionally, if you provide system information and error logs, for example, this would likely help others to assist you.

As a new user, please take some time to familiarise yourself with Forum requirements; in particular, the many ways to use the forum effectively. The following links will help you achieve that.

And last, but not least, the Stable Update Announcements, which you should check frequently for important update related information.

I hope this helps. Cheers.
