It's something about the box64 build. This one from image tag itzg/minecraft-bedrock-server:2024.11.0 works

Box64 with Dynarec v0.3.1 08085be3 built on Nov  4 2024 06:30:46

but the failure above is using

[BOX64] Box64 with Dynarec v0.3.3 a50d34e4 built on Feb 11 2025 06:29:09

Great workaround for those on Macs: use Rosetta and Docker Desktop's support for that:

Latest image installed 0.3.5+20250503.889dd64-1. Need to see if that helps...
