Cause
Rocket Loader is enabled in Cloudflare dashboard. Cloudflare Rocket Loader cuts out several Plesk JS scripts

Disable Cloudflare Rocketloader.
Note: Cloudflare Rocket Loader compatibility was not properly tested with Plesk. It is not recommended to use it with Plesk because it will slow down the interface due to specifics in its source code.

Had this issue today, no matter what I did, the UI completely not loaded. First explored how to pass this problem but then dev panel on Chrome I saw errors about Cloudflare Rocket Loader, disabled and bum!
