Could you share the crashlog?
The output you shared only contains log info.

The thing is that it does not create a crash log. The game hung while loading and I have to kill the instance manually...

Two things you can check:

• Does it also happen when you use 1.0.24?
• Does it also happen when you use 1.0.23?
• Are you running on Graal JDK? If so, can you try upgrading to the latest version?

I tested the 1.0.224-416 and it works.

Java(TM) SE Runtime Environment (build 1.8.0_501-b08)
Java HotSpot(TM) Client VM (build 25.501-b08, mixed mode, sharing)

The below is a new log, still with the issue but only a few mods...

I tested the 1.0.224-416 and it works.

Is that 1.0.24?

If so, then it must be caused by the update to Graal 25.1.3.
Let me try updating to 25.2.4. I'll give you a dev build to try once I managed to do that...
