How do I fix broken inspector in unity?

I added a 3d model to my assets and my inspector started acting weird (pictures incoming).
I tried to open another project and the same happened in it without having the 3d model…
I searched a bit for the same thing on the internet, but I didn’t find anything.
Thank you
