Same issue with windows 11.24h2 - the legacy launcher fix worked for me.

Hi
Could you check your computer for updates and see if the issue still occurs?
Could you also let us know if the issue occurs with newly installed Launcher or one you had for some time?

This ticket will automatically reopen when you reply.

For me: System is freshly updated, Launcher is one that I used for months and it stopped working a couple of weeks ago just like that. Is there any way I can submit some debug info?

Looks like that did the trick for me:

rm -rf ~/.minecraft/

Well, I reported the previous message a bit too early. Launcher starts once when I delete the configs as per my previous post and I can start/play java edition of Minecraft. However whenever I quit the game and the launcher and restart it, I face the issue again:

Issue still there. Any updates? Really annoying to loose login info and game settings upon each game start…

Hi!
Could you upload a video of this issue happening?
Could you also let us know if this issue still occurs in the newest Launcher version?

Hi there!  

Could you answer few questions regarding this issue, it will help with the investigation:  

• Are you logged in in both Xbox app, MS store, and Launcher with the same MS account?  

• Have you tried signing out of all your Windows Apps, and the signing in again? 

• Is your Windows and associated apps (Xbox app, MS store) up-to-date (check for updates regardless)?  

• Do you have enough free space on your disc drive? 

• Have you tried installing the Launcher on a different drive? 

• Please also uninstall the Launcher, delete .minecraft folder (copy its content elsewhere before deletion) and then reinstall, restart your computer. Then please try to boot the Launcher. 

• Do you use VPN or any of the incompatible software on machine you try to log-in?   

• Could you provide us with more in-depth repro steps?

#1 I only have/use Minecraft launcher

#2 I have no such apps

#3 I have no Windows OS in use and thus also no such apps

#4 Free disk space is roughly 850 GiB

#5 No, however the laptop device has only on physical drive, I could try to use a USB-pendrive?

#6 will do so and report back later

#7 No VPN used, no software from the referenceed “incompatible software” list is in place/use

#8 see video above, install launcher on Linux, log in, all works, restart launcher → error

Tried as suggested in #6 to no avail
