Describe the bug
Lately I've been getting popups from the mod as if its the first time I've installed it, locking me to follow its stupid tutorial about how to customize the character mid-gameplay, with no way to EXIT.

To Reproduce
Steps to reproduce the behavior:

1. I assume disconnect from the internet or somehow cause a failure to auth with the mod server.
2. Enjoy being stuck in the menus until it times out or manages to connect and authenticate.
3. (Optional) fall into lava or get wrecked in pvp as a result.
4. Joy.

Expected behavior
Never steal focus or lock the user inside its menus with no way to exit except alt-f4

Screenshots
If applicable, add screenshots to help explain your problem.

Setup (please complete the following information):

• OS: Windows 10
• Minecraft Version 1.20.1 on latest fabric

Additional context
n/a

I can second this. The exact same thing happened me too, I think it was yesterday or the day before. (Using cosmetica-1.20.2-1.2.7.jar with fabric-api-0.91.2+1.20.2.jar and Fabric Loader v0.15.3.) Logged into a server I play on and Cosmetica came up with its full-screen welcome message / tutorial, with no way (or at least no obvious way) to exit from it immediately. Even the ESC key had no effect for going back.

Such a "pop-up" is super annoying, when you just want to play, and what makes it worse is that you can't seem to get out of it. It is a game-breaking issue and thus it should be fixed with a high priority.

Please let users configure their installation whenever they wish, instead of throwing it on their face as a full-screen popup view when logging in the game, especially since it happens also when it just can't seem to connect, even though you've already configured it earlier and playing your game normally.

Thank you for looking into this.

Today, on Sunday Jan. 7th, it has happened twice while playing normally. Last time somewhere around 6:03/6:06 PM UTC.
And again at about 6:15 PM UTC it happened during playing, breaking playing.

This happens halfway through the game when the server is overloaded and can't reach the database to check if you're a new player. You can force disable the tutorial though, instructions here

This can happen multiple times during a play session (without exiting the server) even sometimes in close succession.

Consider adding the instructions here on github as well (a wiki tab) as I and undoubtedly many others had no idea that site even existed.

It's linked on the Curseforge and Modrinth pages. Not gonna add it here since it'll be outdated in v2

See above messages for cause of issue. Not much I can do about it right now so you'll need to deal with it or disable the tutorial until it's resolved

Has this been actually fixed? While disabling the tutorial works as a as a last resort, I figured you'd want to properly fix the underlying issue.
