SAML not working Showing: Unknow InResponseTo

I have setup SAML using google workspace on my domain
But when I use https://crm.my-domain.com/
It shows Unknown InResponseTo ‘_6b026a760b07afe943f44b87d32df905735c9774e3’

Below are the screenshots of configuration

I want to know what is the issue and How can I fix it?
FYI: The normal username/password login is working fine. Issue is only with SSO

Anyone who knows how to make it work?
