After updating to Windows 11, I can no longer access a computer on my network via RDP

After updating to Windows 11, I can no longer access a computer on my network via RDP, even though the credentials are correct. The computers are not part of a domain. It's important to note that another employee, let's call him Danny, can access that same computer. In addition, Danny cannot access another computer in this way - one that I am able to access without any problem. Has anyone encountered this issue and knows what might be causing it?

It's also important to add that I tried connecting via username and password. I tried deleting the cache. I tried restarting the computer. I tried opening a new user on the target computer. I tried checking that we were both on the same subnet. I checked all sorts of settings with IPV6 and a number of other things. Nothing helps.
