I have a Sandbox environment which is constantly failing to work no matter what page I try and access (including Setup pages) and giving this error message in a popup:
Sorry to interrupt
force:showPanel
And this message in the console:
home:5 Refused to execute inline script because it violates the
following Content Security Policy directive: "script-src 'self'
'nonce-null' chrome-extension: 'unsafe-inline' 'unsafe-eval'
https://sfdc.azureedge.net *.visualforce.com
https://ssl.gstatic.com/accessibility/". Note that 'unsafe-inline' is
ignored if either a hash or nonce value is present in the source list.
Before I got stuck with the above message, I got this message:
It does not matter which page I try and load (Home, Setup, Account etc), I will always get the Sorry to interrupt. force:showPanel error.

I believe this was caused by a bug in Salesforce and has now been fixed in our Sandbox.
