[2023] Laucher won't boot up the game after update (microsoft store)

Just to be clear - you all see the launcher itself okay, it is only when you hit PLAY in it this happens?

And you are all on the Xbox/Gamepass edition?  

Ah, so you don't in fact see our launcher.

What if you go directly to where CK3 is installed in File Explorer and double click on ck3.exe there?  

If you've had the game installed for a while, it's probably in an almost unreachable spot deep in C: that MS used to use.

Recently they've changed their mind on that and they are typically installed under C:\Xbox Games\ or D:\Xbox Apps\ . Right click on the game in your Xbox App Library and choose Manage, Files. Does it show a location there?

If not it's probably the first option above. Best to uninstall, then install again in one of those accessible locations.  

mdougla2 said: Based on the error code, do you still advise I uninstall the game or something else?

Yes, I suggest you uninstall and then install in one of those accessible locations, as I described. Then at least you can run ck3.exe if there is still a problem.  

steamnista said: I'm in a similar situation using the Gamepass version of the game on PC. I did reinstall the game a few weeks ago, and I can launch the game via CK3.exe, but yeah, the launcher crashes without an error when at the launching game portion.

So the same as the OP's issue, but not the same as mdougla2's issue, it seems.

Your installation is in one of the accessible locations I mentioned above, is that right?

I do not get any error message from xbox despite failing to launch the game if I try to do it via xbox.
After reinstalling the base game and the DLCs it seems even all DLCs have gone somewhere beyond reach, they are not in my xbox folder, even if that is where they were supposed to be installed.

Do you have the Season pass? If so, I did get this from one affected Gamepass user:

In case anyone else had issues when they purchased the season pass from gamepass.
The season pass shows no downloads and the dlc by itself looks like you need to purchase it.
Click the dlc and click the purchase.
It’ll change and say you own this already.
Click the same box that now says you own this already and it’ll ask you to download it.
Do the download and boom it finally adds
You need to do it for both northern and RC downloads.

Please let us know if that helps you!  

Mööpelitintti said: No, I do not have the season pass, and after uninstalling the game the dlc still showed as "owned" after which I installed them again. But the issue seems to be the main game, not dlc

I'm not sure I follow, you said before the DLC have gone! They are back now?

What's the problem with the main game now? Where did you choose to install?
