Fix a Meccha Chameleon Problem

Friend invites fail, the invite button does nothing, or you get stuck on "Joining…".

The public lobby/server browser is empty or rooms refuse to appear when you refresh.

The game hangs on a login/connecting screen or shows an authentication error before the main menu.

Teammates can't hear you (or you can't hear them) in voice chat, or the mic shows no input.

You click Play, the status flickers to "Running" then back to "Play", and nothing opens.

The game crashes with a "GPU crash dump triggered" error, often while using the brush or eyedropper.

The game stutters or runs at a low, choppy frame rate, especially on laptops or integrated graphics.

On an AZERTY layout the default WASD/ZQSD movement feels wrong or you can't rebind some keys.

You want to remap controls, or some actions have no key prompt and feel unbound.

A subscribed Workshop map won't finish downloading, or mod sync stalls when joining a lobby.

The game launches in Chinese (or another wrong language) and you want to switch it to English.

Steam reports a cloud sync conflict, or you see a "could not sync / cloud save error" prompt before playing.
