[2021] Can't play the game in Ubisoft connect

Hello I've bought Rainbow like 2 or 3 years ago, since then I was playing on my main account. I bought a second copy for my friend to play on my pc yesterday, and since then I can't log into my main account.

The problem lays in the platforms, I bought mine on steam and the second one was on Epic since it was on sale. I can't re-log into another account without fully reinstalling the whole game - which is useless, so my question is, is there a way to not reinstall the game and still log in with steam or should I refund it.

Screenshots with additional explanation:


This is what happens when I log into my main account on ubisoft, I can't play the game

On steam it shows the game as not installed

Same on epic but I can still play it via epic store.


Would there be a way of maybe telling steam the location of the game so I don't have to install it again?

Oh and I still want to add that creating a new library on steam or repairing it didn't work since installing it on epic caused it to have a different location, E:\Tom Clan... not under steamapps common
