Custom commands page not working

Trying to click the custom commands tab shows a loading line up top but doesnt do anything and if i open it in a new tab this is what i see until i click on a different tab that isn’t broken

Hello,
It seems to be a cache issue or something in your browser that is blocking/interrupting the loading process.

Can you press F12, then go to the console and tell me what errors are displayed in the console after refreshing?
