There’s a rather simple way to figure out which block is problematic.

1. Remove all of the code for your blocks. (Paste it somewhere else to keep it safe, of course.)
2. Add code back one block at a time. Check the rendering after adding each block.
3. As soon as it breaks, you’ve at least found the problematic block.

Once you find the problematic block(s), if you need help diagnosing, then share the code for the problematic block definition.
