I was using the latest version and had to restore the old version to get things working again.
Glad to hear the new version works for you.
I'll wait a couple of weeks before updating.
At the moment the old version is working fine.

I reported the issue yesterday.

Opening any page with any video on it crashes the page/site you are visiting.

Had to Timeshift Restore to get my old version back (the easiest option after screwing up trying to fix it myself).
