I want to start Minecraft but after 1 minute it crashes, why don't I know?
Either your pc just can't handle it, or you have too many worlds, texture packs, mods installed.
Maybe this is not the right code. To find out, go to Settings in the launcher and check the box next to Open output log as soon as games are started.
If the "Minecraft game output" window opens when starting, remove the checkmark from info. At the bottom there should be an exit code (marked in red).
If there's the same error code, 1 or -1, let the https://de.malwarebytes.com/...dwcleaner/ run through and try again.
If it doesn't start after that, download https://multimc.org/ and install the modpack there.
