Hello, everybody! I accidentally deleted the message from the previous post, so I'm posting again, sorry. I promise I tried to solve this on my own before posting so not to waste anybody's time, so thank you very much in advance for any assistance!
Ubisoft Connect launches when I click play, but never asks for my Ubisoft credentials. Instead, it just shows the message "logging in" indefinitely and nothing happens because, of course, it can't login without the credentials. I already tried all the suggested workarounds in the fixed post, but they don't change anything. I guess because they're actually meant to just launch Ubisoft Connect before the game, not to fix any problems within Ubisoft Connect itself. I also already installed all dependencies, like the fixed post instructed. Other games from Epic Store run with no issues.
The log from my latest try is attached.
