A Hat In Time not launching

[Cerulean / Nacarat]

As of late, I wanted to restart playing A Hat In Time with a friend using Remote Play Together, I haven't launched the game since a long time ago. Unfortunately, the game takes a long time to launch and even after this and Steam saying the game has been launched, nothing appear.

I don't know what to do, I changed Proton's version multiple time between the Experimental, the 8.0-5 and Hotfix, but nothing happens anyways...

Can someone please help me discover what to do in order to get the game really launched ?

Thanks in advance !

I'm having the same issue! I've been wanted to play a hat in time again but mine crashes before it even starts usually. One time a got a loading screen and it booted up and I was thrilled thinking it would maybe work, the loading screen and animations was very smooth and fast like there was no issue until I pressed once to try and start a new playthrough which it then crashed and I can't boot it up. I've tried to update my drivers and reinstalling the game, even temporary removing my save-file and installing it on another disc but to no avail.
