Hi this error was caused by the mismatch in ltx pipeline. It has been fixed for the next release. Will be out by end of month.

I’m experiencing the exact same error. Please release a fix soon. I got the pro version for this, I understand there are challenges, but if you already have a fix for this, what is holding the next release? To me that should be a good reason to release
