Minecraft Process crashed with exit code -1 when loading a certain world

You are using a modded version of minecraft, which is not supported here.
Unless you can prove this happens in vanilla minecraft, we will not be able help you.
If you want support for your version of minecraft, contact the creator of the mod.

@NewcomerMC I only had Optifine which only enhanced the game (Version: release 1.14.4-OptiFine_F2). However it does the exact same thing in Vanilla minecraft (without OptiFine) as proving by this crash report from vanilla 1.14

Thank you for your report!
We're actually already tracking this issue in MC-12949, so I resolved and linked this ticket as a duplicate.

However, that ticket has already been resolved. Depending on the resolution, that can mean that it either will be fixed in the next version, or that it is not considered a bug and won't be fixed.

If you haven't already, you might like to make use of the search feature in the future to see if the issue has already been reported.
