Extension disables Shortcuts on Slack Web in Arc

I tried the Browser Extension for 2 weeks now. At first it worked everything fine. Now the App doesn’t block the URL anymore (its a slack.com/client url which does not change) and if its blocked, it disables kind of all Slack Shortcuts.

Not working anymore:

• Enter doesn’t send a message anymore (it’s making a linebreak)

• CMD+K etc. is not working

• Keyboard Selection is not working anymore

What i tried:

• Clear Application Storage of the page (cache, cookies, sessions) → not fixing

• Disable the Extension → works

Thats why i think it’s the Browser Extension which causes the error. I’m on the latest Arc/Chrome Build. There are no console errors visible.
