I'm not the OP but I just ran into the exact same problem. This is the log I got when I picked up a chest and tried to place it into a vanilla crafting table.

When I load back into the game the chest is placed on top of the crafting table though. So it get's placed but something with the rendering causes it to crash.

Here's a log with only Carry On installed. Hopefully this simplifies it for you a little bit.

Shouldn't opening GUI's be prevented while carrying something...if both hands are in use carrying a chest, then how are you able to "open" something else

It should. This is how it works on 1.12, but it looks like this doesn't work anymore on 1.14...
