A potential solution has been determined, this may resolve your problem:
- Replace mod 'Polytone' (polytone) 1.21.8-3.5.4-alpha with any version that is compatible with:
- minecraft 1.21.10
More details:
- Mod 'Polytone' (polytone) 1.21.8-3.5.4-alpha requires any version between 1.21.8 (inclusive) and 1.21.9 (exclusive) of 'Minecraft' (minecraft), but only the wrong version is present: 1.21.10!
