Communication Error between adapted lens and body.

Hey all, recently I was able to get a good deal on a vintage Contax Carl Zeiss 28mm 2.8 and I had seen it was an EF mount body and having an EF-RF mount, I assumed it would work perfectly fine as every single EF lens I've gotten so far has (4th making this the 5th) and the brands are all different and different types (primes and zoom). I started to get the communication error, stating there was an issue between the lens, body, or adapter.

I saw a fix on reddit saying that going into the settings and turning on "release shutter without lens" was the typical fix for this, and upon doing that, my camera worked for 3-4 shots before the communication error came back up and it would essentially freeze my camera afterwards, sometimes having the only fix be turning it out and taking out the battery out for a second and putting it back in.
Would anyone be able to help me with this? I'm running on a Canon ROS RP.
