Slow application startup

Hey everyone,

I created a Bottle for the Ubisoft Connect launcher and respective games. The launcher starts but it takes a pretty long time to be usable. It takes around 30s until the initial window appears and another 30s to be usable.

Is this normal behaviour or should it be faster?

This is the log when I start the Ubisoft launcher in the bottle:
