It does look like it really depends on how the app is built.
I tried to create a ticket for Apple today, since I'm getting this as well, and created a very simple Swift app with just one TextField, and copy/paste actually worked fine.
On the other hand, in the React Native app, clipboard is completely broken and I'm getting these sort of things… Not sure how to decipher what I'm getting, but I was building off the same codebase on Intel before I switched to M1 (when it started to happen), so one thing I'm sure of if that something's definitely up with M1 simulator thingy…
