By logs, I meant mcpppp logs :p
Can you send those as well? It should be mcpppp-log.txt
Also what were you doing when the crash happened?

I was trying to convert the skybox textures, i pressed start, it then did something for 10 seconds and then crashed

Thanks, now can you send the resource pack you were trying to convert

I can't reproduce this issue. It took forever to zip and unzip, but it didn't crash. Can you maybe try unzipping the pack first, then converting the unzipped one?

Also if you need the pack urgently, I've converted it for you: https://www.mediafire.com/file/5ik2r5fk3txo7uv/Misa_1.18a.zip/file

Could this be a libc(++) mismatch issue?
