it crashes the game, then it doesn't allow Ubisoft Connect to send the crash report to Ubisoft. the only way to fix it and being able to play, was to remove NextDNS from IPv6.
Have you tried using ipv4 ?
Greg B. By disabling IPv6? No.
I've checked the logs and added everything Ubisoft related to the Allow list. But this shouldn't be an issue by default.
