I get the following error in Windows 11 when I try to connect to a certain computer with Remote Desktop. It was working fine before I accidentally selected delete credentials. Now it refuses to connect and not even a System Restore could fix the problem. My laptop and other PC can connect to the remote computer without any problems. What can I do to fix this please? Strangely enough Remote Desktop works fine when creating a new user account on the affected machine and using it under the new user account.

    my fix to the exact problem is very simple, click the button 'show options' untick all the checkboxes in General/Display/Local Resources/Experience. it then worked, and I then tick those options where I needed, everything's sorted!

    I solved my issue in a radical way, maybe this will help to find a bugfix:

    Because it was a new PC with a fresh Win10 installation from Sunday (honestly an old version from 09.2017 which I upgraded to latest possible, in my case 20H2).

    Everything was fine, RDP made a good job with the latest Win10 20H2 version.

    Two days later I made the Win11 upgrade on Tuesday and the reported error appeared. I just installed a few programms on my Win10: LibreOffice, Tracker PDFeditor and old versions of OneNote (Desktop) and Adobe CS.

    Because I found no bugfixes online, I decided to waste no time and go ahead with new installation:

    First try: Win11 repair with keeping all personal data > no effect, problem was still the same.

    Second try: Complete fresh Win11 installation with formating the HDD > After that and also after installing the same programs, the mstsc.exe RDP programm worked without any problem.
    EDIT: I forgot, I installed 7zip on Win10 but not after the fresh Win11 installation.

    Obviously it a problem with the Update and not with the mstsc.exe or with the account in general. The MS Store RDP client (which is really bad) worked. But this is not really a solution for a full dialy use and if the fullscreen without the task bar of the local system is needed.
    Hopefully this will not happen again with a later Win11 update.
