Same here. R25 MacOs 12.3 M1 Max.
I wrote a ticket to the support and I tried (multiple times) every suggestion that they gave me. At first, seems to work, but then stops as before.
If someone wants to try, those are the instruction from support:
Uninstall Chaos Cosmos by going to /Applications/ChaosGroup/ChaosCosmos/uninstall/Uninstall
Make sure that the following folders no longer exist once you uninstall Chaos Cosmos
~/Library/ChaosGroup/ChaosCosmos and /Applications/ChaosGroup/ChaosCosmos/
Download and install the latest version of Cosmos Browser
Note: I'm on a fresh install of macOS, Cinema4d and Corona. So I don't think that the problem could be related to old junk or similar.
