This is more informational than anything else, in case anyone sees the same behavior.
I had issues with GP crashing on my M1 MacBook Pro, and per crash logs it appeared to be Omnisphere. I reached out and provided them all the info, and they verified that it was an issue with Omni. Two days later I had a patched version to test, and it appears to have resolved the issue. Assuming the fix would be included in an upcoming update.
