Error downloading Apple Intelligence on 15.2 Official Release

Hiya, struggling to download apple intelligence (again!) Had it all working before but the download gets stuck at 100% on the official release (same with image playground) and going through csrutil, and deleting GenerativeModels doesnt seem to work right now (Not sure if I've targeted the wrong directory, but copy pasted what worked before.) Any way I can completely wipe my Mac of the generative models files and start again, in hopes it will maybe help being able to finally use ChatGPT integration, image playground etc? Macbook Air M2
