I started getting the "An internal server error has occurred" error when I try to change Object Field Permission in a Permission Set in my Dev Org.

So when I am in a Permission Set and try to change some Object Field Permission I get the next error (in both Lightning and Classic):

An internal server error has occurred

Error ID: 78463948-26707 (138448630)

My Permission Set is a part of Managed Package. However I even get this issue if I try to changes field permission in a Permission Set which is NOT a part of Managed Package.

I have tried suggestion from this question: " An internal server error has occurred" - While Assigning Apex Classes to Permission Sets :

I changed next features in User Management Settings:

  • Enhanced Permission Set Component Views
  • Permission Set & Permission Set Group Assignments with Expiration Dates
  • Field-Level Security for Permission Sets during Field Creation

And I compared the setting with the one in my another Dev Org, where everything correct, however I could not find anything that could help.

Also I tried to:

  • Clear browser cache
  • Try a different browser
  • Disable browser extensions
  • Use incognito browsing mode
  • Check Salesforce Trust - everything is good here
  • Verify my user permissions - user has the necessary permissions to modify Object Field Permissions in Permission Sets

But error is still there.

We created a case with Salesforce Support, however I want to know if there is something we can do with this before we get response.

Any help will be appreciated,
Thank you

This GACK stacktrace(138448630) has been reported by multiple customers too.This happened with the Summer'23 release. The stacktraceId corresponds to the error based on backend logs ApiQueryException: SELECT PermissionSetGroupId FROM PermissionSetGroupComponent WHERE sObject type 'PermissionSetGroupComponent' is not supported. If you are attempting to use a custom object, be sure to append the '__c' after the entity name. Please reference your WSDL or the describe call for the appropriate names.
