I love this mod, but my game crashs every 5-35ish mins. Can anyone help me find out why?

Every time I try to click on "manage saved files" to spawn something I get this error and about 20 seconds later my game crashes. I have tried deleting and reinstalling everything, and that didn't work. For the life of me I can't find anything online about this specific error. If anybody knows what's going on I would appreciate some help, thank you.
