Thank you for your report!
However, this issue is Invalid.
You are using a third-party launcher. If you can reproduce the issue in a vanilla environment, please create a new ticket. The official Minecraft Launcher can be downloaded here: https://aka.ms/minecraftClientLinux
Any nonstandard client/server/launcher build needs to be taken up with the appropriate team, not Mojang.
A world which had previously been opened with a modified client might be corrupted. Please try reproducing the issue in a newly generated world.
Any plugin issues need to be reported to the creator of the plugin or resource pack.
If you have problems on large servers such as Hypixel, please contact them first as they use modified server software.
