[2022] An error with the in-game overlay of Ubisoft Connect

When i was playing Tom Clancy's Rainbow Six Siege i noticed that after i press Shift+F2 to open the overlay and accept the invitation from my friend to play together, the game starts to framelag, and i noticed that when I open the in-game overlay, the last starts to use a huge quantity of CPU percentage, taking over 50% of CPU in some cases, and this causes the framelag, but if i change graphic options and return back my standard graphic options the process of the overlay stop using a lot of CPU, but if i open it again, it starts again with the same problem, and i tested this in all my games and noticed that this problem occurs in every ubisoft game that support the overlay, even The Division and some Assassin's Creed games... As you can see in this case i tried Rainbow Six, and after opening the ubisoft overlay by clicking shift+f2, Ubisoft connect normally starts to take around 40% CPU, some cases it uses over 50%... i tried a lot of solutions like sending to the support the MSInfo file, DxDiag file, changing some settings in the game, but nothing of these solution works... so i started thinking that the problem may be of the launcher, cause another my friend has the same problem with the launcher...
