So i downloaded the latest mcreator update and all my mods just work suddenly. When I create a new world in mcreator minecraft with my mod, it says "Data pack validation failed" and in the world, no structures, biomes, ores or mobs generate as they should.

Did you install the latest patch update and re-import the workspaces in this version? This was caused by a bug when converting fluid generation to the new feature mod element

Did you install latest patch update?

UPDATE: We have released another patch update to fix some more bugs found in the 2023.1 release:

2023.1.10610:

[Bugfix] Forge 1.19.2 workspaces ported from earlier versions with fluid generation crash the game

[Bugfix] Repeating fields and inputs were not validated properly if they were empty

[Bugfix] Some other minor fixes and improvements

To install the patch, re-download 2023.1 and install it again. Make sure to uninstall the current version first.

If you did, make sure to open the workspace again in this version, but a version before you opened it ever in 2023.1.

If you don't have such a version, go to <workspace folder>/.mcreator and use the latest backup ZIP file from there and import that ZIP into a new workspace folder
