Can no longer see my project after starting OAuth migration

Hi,

I began the steps to migrate my JWT credentials to use the OAuth S-S credential.

I clicked the first step to begin the process, however now I am unable to get back into my project to continue - the page just loads up blank.

When I refresh the page, I see the project load momentarily but then the page just goes blank. Tried on multiple browsers, even as a different admin but still no joy.

All I can get is a blank webpage when I'm in my project developer.adobe.com/console/projects/...../overview 

I can create a new project and get into that but not continue with my already set up project.

Anyone else had this?
