Minecraft Launcher fails loading

Upon opening the Launcher, it gets stuck on the loading screen as shown in the screenshots. I have also uploaded my launcher logs.

 

To recreate:

Perform a clean install (or use your old configuration, I don't think it matters) and open the Launcher. You should see the loading animation over and over.
(If you did a clean install, on the second launch the Launcher will get stuck.)

 

Attempted fixes:

1. waiting 10 minutes
2. restarting PC 
3. updating drivers
4. clean install of Minecraft (temporary fix)
5. reinstall Minecraft altogether

 

Unfortunately the only way to play Minecraft is to do a clean install which only works once.
(After a bit of testing I found the problematic file being the "launcher_accounts_microsoft_store.json")
