Problem:

Launcher tries to update despite being completely offline, when run outside the launcher, Bedrock gets stuck on 40%.

Result:

The game won't run at all. Currently I'm having issues with my ISP and as such, now can't use a game, which I paid for (not through game pass). 

Error Message:

Before being stuck on "Waiting for install" despite no install taking place and not being able to connect.

Additional Notes:

Due to windows' aggressive upload of device data, and the fact it is electrically intensive to do so, I don't want to have to hotspot from my tablet's limited data pool of 125GBin order to play the game, please fix the launcher so it can be used offline, as it is supposed to do.
