@Markus S Thank you for reaching out to us, similar issue has been worked upon by one of our support engineer last week in that case I see installing the below KBKB5041585 has helped to resolve the issue
would request to review the pre-reqs of these updates as per your client operating system.
Once the update is installed reboot the system and verify the issue.
Let me know if you have any further questions, feel free to post back.
