@avi12 My previous comment is not longer accurate, they pushed a fix to the browser. All the extensions are working now.

@avi12 are you on core: 94.0.4606.64 tho? I have the same problem and it's not your extension, half of my extensions stopped working right after updating to this version.
They are installed but unavailable in every sense, like they don't exist. Tried removing them and installing again, nothing works. They are installed and enabled but thats it, they literally don't exist, can't even access their options panels. I don't know what this update did and how to fix this.
