Hmm, that is strange. I have not seen or heard of this error for 110. What is exact version? 110.1?

My recommendation is to do a hard flush or the OV folder in your users folder and start fresh. That will clear out any stale issues. I just built 110, so I know it ok

Ah, I should have tried another machine. Something corrupted my cached extensions. Deleted it and re-built. It’s working fine now.

Good to hear
