I give it to play and it starts to load then it designs an unexpected error has occurred and the game has stopped working.

https://launchermeta.mojang.com/v1/packages/93f435ca0c67eff15eb81a0f4aa234708d6b34c9/1.15.json had an invalid checksum. Expected: 93f435ca0c67eff15eb81a0f4aa234708d6b34c9 has: 8af60440f8a814f5b1c752adefb7dfae698c9f77

and if I put it in chrome it says that what the code says is access denied
