New install: Why are these popup menus appearing, hiding my code, and why can't I get rid of them?

I have used PyCharm and other products like IntelliJ for years, been happy and never had problems like this. Previously, I've used Intel and M1 macbooks.

Today I downloaded PyCharm Community on a new Mac (M2 chip if it matters) and PyCharm is completely unusable due to some "helpful" (?) menus appearing as soon as I write any code. The menu covers the code so I can't see what I'm doing. It's not clear what these menus are meant for, and they don't disappear when I click on them or outside them.

Is this a new "feature"? Is something wrong with my computer? The computer is brand new and fresh installed.

Attaching a screenshot of what's happening.

If I keep typing, more menus appear and stack on top of each other.
