crash on boot after instore purchase

After i have bought something from the store my minecrat crashes and dies, when i try to load it again it gets to the main menu and then crashes. this can be fixed by disconnecting the internet booting the game and then reconecting it but i have to do that everytime i launch the game. i have read arround and found one other person with this issue and the things we have in common is our cpu a 8700k i think this may be the issue as it doesnt happen on anyother p on the same account(ive tried 2 others). If you need any further details just ask as i can reproduce it. the issue doesnt go away after a restart of the computer and i have tried all troubleshooting that i can think of (loging out loging in reinstalling etc). thank you for your help.

this only happens after interacting with the store it was fine beforehand.
