I was in the middle of making a mod and suddenly all the textures stopped showing up.

https://moddingtutorials.org/1.19.2/basic-blocks/
I was trying out the tutorial and all of a sudden the textures stopped showing up. I had created a few items and a block, but when I tried to add another block, this happened.

Here is a log that might be relevant

What we tried
This error appears when a block is added (creation of a json file for the additional block), but deleting the block-related files and code does not recover the textures.

I was able to reproduce this bug in another project.
What I did was to change the name and modid, then run gradlew genEclipseRuns, copy itmeinit, blockinit, assets and add the line .register(modEventBus); in the main class
