Some other dudes have been telling this too.
Out of curiosity, can you check your Windows 10 Settings for Game Bar, Game DVR and Game Mode - do you have them all 'OFF' or 'ON' or a mixture?
Whenever you have time.
On by default.
Game Mode is now part of the Game Bar and Windows Game Recording and Broadcasting feature.
Technically, if you turn off Game Bar and Broadcasting in the Settings app, it should stay off.
I prefer also to set the local Group Policy object (Computer Configuration - Administrative Templates - Windows Components - Windows Game Recording and Broadcasting) to "Disabled".
