I use Faugus launcher. I have Ubisoft Connect installed in Faugus launcher. Game The Division 2 requires Proton 11 to run. But Ubisoft Connect won't even start with Proton 11.

Proton 11 has a known regression in the NTSync/ESync interface on Linux that causes the Ubisoft Connect client to crash immediately.

Just add launch arguments to the Ubisoft Connect launcher

PROTON_NO_NTSYNC=1 PROTON_NO_ESYNC=1 %command% and voalá Ubisoft Connect launcher start properly with Proton 11.
