My website crashed after I installed Yoast SEO, what do I do?

I have been using rankmath plugin for a while now, but decided to try out Yoast SEO as I have heard a lot of good things about it.

Now Immediately I installed it I got the error  ‘There has been a critical error on this website.”

I have tried everything including changing PHP version but the error still remains.

I really want to try out this Yoast SEO plugin, and would appreciate any advise on how to fix this error, as I do not want to go back to rankmath SEO.
