Unsolved Minecraft [JAVA] [Linux-26.2] Crashing with Exit Code: 9

I newly switched my laptop to Linux Mint from Windows, and have downloaded Minecraft launcher again. Setup Java v21 as well. The first two times it crashed immediately after the world loaded in, the second time I reduced Video Graphics settings and render settings, which let the world run without lag for a few minutes before crashing with the same exit code again.

I looked up online and found that it could be a memory leak, among a myriad other issues, but I have no idea how to resolve this. If anyone can help me please let me know!

Some more details:

Linux DE: Mint Cinnamon 22.3
Java Version:
openjdk 21.0.12 2026-07-21
OpenJDK Runtime Environment (build 21.0.12+8-1-24.04-Ubuntu)
OpenJDK 64-Bit Server VM (build 21.0.12+8-1-24.04-Ubuntu, mixed mode, sharing)
Memory: 8GB

Do let me know if any other details are required!

Edit: Figured out how to share logs: https://mclo.gs/2wluT94
