Problem:
you can't create a file on a Windows pc like COM8/COM7/...info and LogisticPipes try's to because my ingame name is COM8 to save some stuff in it.

Possible solution:
Don't use ingame names for this it would be better to use the UUID or something else :D.
So everybody can play again without crashes.

Crash Report:

yeah, we already talked about using the UUIDs in the future.
