Confirmed. Inf ammo does something to the game that triggers crashes or freezes. Usually happens when engaging VATS. After leaving it off, game ran fine. In any case, just use the 'player.additem(space)itemID(space)amount' without the apostrophes. Here's a list of ammo BaseIDs: fallout.wikia.com/wiki/Fallout_4_ammunition
Also, one for the items which includes building and crafting resources: docs.google.com/spreadsheets/d/1J9quAMtGK70aptz0t5teqWHGZJ9T9uvJmzNEBJEB36Q/htmlview?usp=sharing&sle=true
As for the free crafting for the settlement building mode, the items to build won't be buildable/won't appear if you don't have enough resources in stock even if the cheat shows 1000 of the resources. This is basically the same as 0. 1001 means you only have 1 while 1025 means you have 25 in your inventory and so on.
thank you very much!!! saved my life!!!
