Not a Cyberware issue. When you acquire your first implant, you receive a note with it, this triggers a crash in one of DLL plugins.
(Posted on the TTW Discord.) The crash may be caused by NVHR. Go to Fallout New Vegas\Data\NVHR and replace nvhr_avx2.dll with this one. If the issue persists, make a copy with name nvhr_avx512.dll and copy it, too.
(Posted on the xNVSE Discord.) The crash may be caused by multiple SetOnNoteAddedEventHandler listeners. Get this Wall_SoGB's build of JIP LN NVSE from the xNVSE Discord. Or install a version above 57.21, whenever it comes.

Got the same issue as blazingwolffang and replacing the .dll files didn't help. The game was still crashing whenever the first acquired implant was bought from a store.

However, if said first implant was gotten as a world object (like the one from Doc Mitchell's house), the note was added with no issues and there was no crash.

Iirc there was also an issue with the "Hide Equipped Items in Barter" Stewie's Tweak, try to disable that.

Cyberware cannot cause a crash, because it's an OBScript mod, it simply does not work on a level sufficient for that. It's always an issue either in the engine, or in a DLL mod.

Just checked, that one setting was already disabled. In the meantime, finding an implant in the world will be my workaround. But I appreciate the suggestion.
