I have Ubuntu 22.04 and Opera 91.0.4516.77, which I installed through snap. Something broke and now I can't install or update any extensions. I get this error when I try to install an extension on the Opera website: "An error occurred when installing the extension: Page was closed before download started".

When I try to search for extensions by going to Opera > Extensions > Get Extensions, nothing happens.

Also, it appears that I can't update Opera either. When I go to Menu > Update & Recovery, or Opera > Help > About Opera, it just hangs on "Checking for Updates..."

I'm not sure if these issues are connected or not, or how to fix them.
