GPO printer forwarding, question about it

Hello all,
We have a terminal server (ERP) on which the users connect via RDP.
Previously, the user was also forwarded his local printers, this is no longer the case.
But if a user logs in who is a member of the local admin's, his printers are forwarded.

We are already looking for the GPO that makes the difference between the printer forwarding between admin and normal user,
so far no chance to find it.

We also see this error message for these affected users:
event 1306 Connection Broker Client failed to redirect the user... Error: NULL

Therefore the question, which GPO makes here this restriction depending on the membership local admin or not ?

Thanks for any help.
Stefan

    Hello Stefan,

    This seem to be related with the latest update 20H2 regarding the Print-Nightmare zero-day issue.

    I will recommend you to check the printer assignment and restrictions as per Microsoft KB:
