Description of the issue:

When opening an inventory that happens to have a tool shader, be it though pressing E or something else that shows inv (such as opening a chest), the game crashes. However clearing the inv fixes it.

Is this a 1.12 world that you loaded in 1.14?

I -think- it might have been, was porting some structures across versions so I may have opened a 1.12.2 world in 1.14

1.12 and 1.14 are not compatible.
In 1.12, IE's shaders used a different way of storing their data which leads to conflicts in 1.14.
