This looks like the same issue I'm reporting in MCL-8730. It does not create a crash report, but the launcher_log reports that the game is unable to access the refresh token.
This has been happening for me since I tried logging on back on 12/18.
I have attached the log and the error from my event viewer in my issue report.

This is from Minecraft: Windows 10 Edition.
Thank you for your report!
However, this issue is Incomplete.
Your report does not contain enough information. As such, we're unable to understand or reproduce the problem.
Please review the guidelines linked below before making further reports.
In case of a game crash, be sure to attach the crashlog from minecraft/crash-reports/crash-<DATE>-client.txt.

I've attached a screen shot of the crash report folder. There is no crash report being generated. According to the launcher_log.txt, the launcher is just timing out and shutting down while trying to refresh the access token.
What kind of additional information do you need?
What exactly happens? You said "The launcher crashes to desktop", what do you mean by that?
I click on the icon... the launcher starts, I see the Mojang splash page on the launcher for about 3 minutes, then the launcher just shuts down.
It's been doing this since i tried to play the game on the 18th. I kept hoping a new release or patch would be pushed out, but it never happened.
I see several other open tickets complaining of the same thing, but they were all closed due to insufficient info, and none of them posted any additional info for the dev team to investigate.
Is there anything else I can check or any additional info I can give you to help track down this issue?
Yes, can you link me to the reports you think describe the same or a similar problem as yours? Also, can you attach a screenshot of the contents of your .minecraft folder?
You said you see the Mojang splash page, so it is not the launcher that crashes, is that correct?
These reports all seem to be referring to the same issue I'm seeing:
MC-123668MCPE-14372MCL-8728MCL-8710When I get home I will update this ticket with the screen shot of my .minecraft folder.
And yes, it seems to be the launcher that is "crashing". See the launcher_log.txt file I attached when I created the ticket. It seems to show the launcher trying to refresh an access token and failing. It says "Staying on the log in screen". It then waits about 3 minutes and shuts down (crashes) to desktop.
From the attached launcher_log.txt above:
[1227/230237:INFO:ClientHandler.cpp(859)] App: Failed to refresh access token. Staying on login screen.
[1227/230516:INFO:ClientHandler.cpp(149)] Shutting down!
In the launcher log, I don't see anything out of the ordinary except that your access token ran out.
MCPE-14372is entirely unrelated as it's about another edition of Minecraft. The other issues don't necessarily have much in common with yours, they all haven't responded yet. There are many different issues with the same symptoms.To understand your issue better, it would also be good if you attached some screenshots or a video of what's happening when you start the launcher.
Fair enough, as I was searching, the symptoms just seemed to be very similar.
I've made a video showing what happens when I start the game, but it exceeds the 10 mb limit. is there someplace else I can upload it? Or can I send you a link to it in my dropbox?
That would be possible, you could also upload it to YouTube for example.
I've uploaded it to youtube.

Thank you.
No wonder I've been confused all the time, you tried starting Minecraft: Windows 10 Edition, which is a branch of the Bedrock Edition (previously known as Pocket Edition).
This tracker is for the Minecraft: Java Edition launcher only.
Please report this issue to the Bedrock Edition bugtracker, after checking whether it has already been reported there.
Ahh.. gotcha! I could swear I mentioned that it was Minecraft Windows 10 in the initial comment. Sorry for the confusion.
I will move this over to the other bug tracker. Thank you for your help.
