This is a 1 off to me, I use the bench all the time, it works fine. Just felt I should report it.

Describe the bug
Was making a TF reinforced upgrade in the projectbench.

To Reproduce
It seems to be a 1 time thing.

Expected behavior
Not to crash when crafting item

Crash Log

Versions
Everything in the pastebin

Crash log link seems to be expired. This is probably fixed at this point anyway, since a lot has changed with the project bench. Open another issue of you see more crashes in 1.15+.
