Tried the web version on my Macbook Air (2015 model, i5, 8 GB, macOS Monterey). With Safari the page crashed and reloads, with Firefox the loading screen freezes at a certain stage. I can't see any unusual CPU or RAM usage spikes prior to crash.
Do you see anything in the developer console? Should be Cmd + Option + C
There are two error outputs (with a bunch of warnings) in the console that might be relevant:
Error: Promised response from onMessage listener went out of scope 3 background.js:931:170
and
Cross-Origin request blocked
