Where does the page builder save the templates it creates?

Hi there,

I was fiddling around with the page builder trying to understand how it all works and i seem to have done something it didn’t like. I placed a Parallax block in the builder bit, set a photo to it from the ones i had previously uploaded, then added a column block inside the parallax one, i did not put anything inside the column block.

Since then the page builder part of the admin panel wont load, just gives a white page, i figured that i could just remove the offending template, but have no idea where to find it, be it it’s own file or as code in another.

Any suggestions?
