Describe the bug

I am using argocd version 2.12.4 for one of my project. Everything used to be working fine and suddenly one day I am not able to enable or disable autosync from UI with all users even as admin users. Using argocd CLI it is working as expected.

To Reproduce

Click on the application details in argocd UI -> Click enable/disable autosync

Getting the below error in UI (even as admin user)
Unable to "Enable Auto-Sync:: <TITLE>Access Denied</TITLE>

Access Denied

You don't have permission to access "http://argocd....***.eu/api/v1/applications/loki?" on this server.

Can you share your argocd-rbac-cm, please?
Also, the error might be about permissions accessing URL, not ArgoCD denying access itself.
