I am getting the same message and am unable to make a movie containing audio either in Premiere or Media Encoder.
Here is the message I get:
Audio Filter missing: 1095582513 MultiBand1
It looks to be the same one.
A month later, I'm still having this problem. Anybody have an answer? I haven't been able to find a solution online.
I have a suggestion you can try: Reinstall Pr.
