[2021] [Bug/Glitch]After launching Rainbow 6, after around 20 seconds the game minimizes itself

Hi Rayndown! I'm sorry to hear that you've been experiencing this problem with Rainbow Six Siege. Can you please try verifying the game's files in Steam? Doing so will replace any missing or corrupted game files that could potentially be causing problems. I generally recommend completing this process after patches for the game are released, as it ensures that everything required for the game was installed correctly during the update. Afterward, please complete the remaining steps listed in our technical troubleshooting guide. If none of these suggestions help, can you let me know if you've recently changed any of the game's settings? Also, did this start after a specific update or randomly?
