AdBlock not staying enabled in 4.8.5

[Swiftyrabbit]

I upgraded my Lite version from 4.8.3 to 4.8.5. Now AdBlock won't stay enabled. Here are the pertinent details from the log:

I saw similar Issues but they seem to be related to the ghostery package or other circumstances. This seems to be a different problem. I also tried updating NodeJS to the latest version but that didn't help. Any idea how to get this working? Thanks in advance for any help you may be able to provide!
