Extension was turned off because it is no longer supported

Opened Chromium with a pdf and this comes up "This extension was turned off because it is no longer supported" on uBlock Origin development build.

So what are our options for Chromium?

Temporary bandaids I know, so what next?

I set the chrome:flags to allow v2 but I know this is just a matter of time.

edit: It is impossible to open any site without uBlock Origin
