Breath. server crashes on startup – what to do?

Breath. officially supports datapack, fabric, forge, neoforge, quilt for Minecraft 1.21.8, 1.21.7, 1.21.4. Note: Forge and Fabric mods are NOT cross-compatible – pick one loader and stick with it. The Mado dashboard automatically detects incompatible loader combinations.
Server lagging with Breath. – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Breath. consumes the most tick time.
