[2021] Game won't end (Steam Rainbow Six Siege)

So this issue has been reoccurring non-stop for the last few weeks of me reinstalling Rainbow for like the 5th time, though this is the first time this has ever happened. I am not sure if this is an issue based on the new update to the game or rather a long-time-running issue that has yet to be resolved. Knowing how Ubisoft is, I'm unsure if this will ever get a reply but this is the problem, after a day of playing Rainbow, while trying to close the game I successfully end the game itself but when I check my Steam tab, it always shows that the game has yet to be stopped. As such the game always shows as open and it stays like that for a while until I either try to uninstall it which fixes it momentarily but it comes back again, or I try to use task manager to end the game but then I have to constantly relog, and until today, the game doesn't even start at all. I don't have a clue what's causing it and I have no clue to a permanent fix so I hope, someone will be able to help me resolve this annoying ordeal that has been bugging me for a while, thank you in advance.
