I'm having the same issue. I tried to replicate it and seems that I get this error more often when doing these steps:

• Open a couple instances of structurizr on Chrome incognito (not tabs)
• Sign-in into both and wait some minutes
• Sign-out from both but keep instances opened
• Open a new instance of chrome incognito (not tab) and sign-in
• Error pops up

I have the debugged the SAML request/response and I wasn't able to find any issues when this error pops up
