Unable to click and drag anything in Resolve 16

I'm unable to drag anything into my timeline. Doesn't matter the file type, nothing works. It's as if Resolve 16 isn't recognizing that I clicked at all when I try to click and drag files or even effects onto any part of the timeline.

All tracks are unlocked, position lock is off, I'm running the program as administrator.

This issue started after the program randomly crashed on me when I was trying to make an edit on a (very simple and uncomplex) video. After the crash, I reloaded and I'm unable to drag anything. It registers me clicking, so I can highlight things and click on menu buttons and such, but trying to click and drag files or effects has no effect other than selecting the file or effect.

Can I check if a. it is a collaboration project, b. if it was loaded accidentally in a read only mode?

I am sure that this problem can be solved easily. Pay attention to the FAQ section. That's the only thing I can recommend.
