'Project files not associated' how to fix it?

uproject files are not associated with this launcher, would you like to associate them now?

when click on fix now it does not resolve the issue , it shows again when launches the epic game launcher.

And all the uproject files icons are in black not in blue, when right click on these file 'Generate visual studio code; option does not appear.For this , run the UnrealVersionSelector file in UE_4.25\Engine\Binaries\Win64 but that does not help.

Maybe this is related to epic game launcher error. So, trying to fix this.

You can manually add it with regedit. There is something about adding that stuff manually. Just be sure you know what you do before messing with windows registry. Manualy start regedit and navvigate to those keys, check if they exist what is inside etc.…ects-uproject/
