System has been stable for months no adjustments being made and suddenly “Plugins” Crashes and I get the below error? Any ideas how to fix ?

There is no integration called “plugins”. Remove it from your config.

Thanks, Can I ask how ?

Can’t access
File Editor or Studio Code Server as the none of the plugins work

I’ve not touched anything on the system for 4 weeks as I’ve just been using it and its been working superbly so this is all a little odd.
