Trying to stop my urge to ask, but... why doesn't upgrading it work? That sounds a bit odd.

[unknown] but... why doesn't upgrading it work?

Apparently too big changes that cannot be fully automated correctly.

For small projects it kinds works and maybe a few small things are broken that you can fix. For a whole game it just corrupts it and doesn't work at all.

From what I have been told, huge portions of Godot code were rewritten from near scratch, and GDQuest on youtube.com isn't exaggerating too much in their video title .."It's Almost A Brand New Engine!!".
I would have stayed in Godot 3.X, however Godot 4.X had multiple features I had to hack into the version I used. At some point I decided I was saving more time and the player more processing power by upgrading, but I was right about only one of those things. It wasn't time.

I did face godot crashing once, after a few minutes I notice blender crashing also, so it was because some glitch in a 3D model I had, fixing the model fixed the crashing in blender and in godot.

[unknown] Confirmed- I am not alone with the crashes on the Steam version.

Which just confirms that Steam is evil.

It's not a great idea to use the Steam version anyway, since it auto-updates. A lot of people lost their projects when Godot auto-updated from 3 to 4 and they weren't using source control

a month later

I'm having this issue as well, just tried the 4.1.1 version, but it crashed when trying to create a new project 🙁
I'm on Windows 11.

Version 4.0.3 works for me though 😛

    DaveTheCoder Shocks, version 4.2-dev3 also crashes when creating a new document. I will do a bug report soon, thanks

      Was having very frequent crashes on 4.2 dev2, whenever u trigger a script runtime error or missing node/null scene.
      Though never crashed upon project creation. I am on win 10 though.
