Fallout NV crashes!!!

[LeROI10x]

I do not know why, but in the game, when I equip an outfit or cloth modified with outfit studio, the game crashes and only closes without leaving a message, but I can't find the error, please, if someone can help me with something, it would be very Thankful, I've already made other conversions without any problem.
I used the google translator to write this, cause my english is very bad.

i had this issue.. in my case i had to reinstall my body mods.. also the crash can be caused by the cloth mod your using. make sure the mod is compatible

Yes, as Geostorm69 said, some nifs will not work in BodySlide. I had this problem with several. One thing you can try is saving the nif file in Nifskope. Always make a copy of the original nif file before trying it in BS/OS.
