A way this used to be possible, also before win11, was misbehaving custom extensions to the explorer shell. IE, some applications install extra menus and handlers as part of the windows shell.
Particularly, some such extensions may fight with each other - you can have one installed, or the other, but not both.
I use the tortoiseGIT extension to integrate git into explorer, and a lot of the bugs it has seen over the years, have really been work-arounds to survive OTHER broken explorer extensions.
My point being, the problem may come from one of your staple applications, not from the fresh window install(?).
I have several tools installed, also such which hook into explorer, but not more than I had with Windows 7, which I replaced last year with Windows 11 on a much more modern machine.
Two weeks ago I had to boot into the Windows 7 on the old machine (it now boots into Linux by default and I use it occasionally) and almost tears came to my eyes when I saw how fast that 13 year old machine is.
