PIM wont activate

I've got a problem in PIM - when I click on a role to activate it it just sits at LOADING and the activate button doesn't ever come live.

I've got MFA turned on as well and my account is authenticated.

This has only just started happening, it's been happily working for months.

 

I've tried different devices, browsers etc.  Same issue.

 

Anyone seen this or can help?
