I have tried the following fixes without any success:
- Downgrading New Vegas Heap Replacer to 3.1 and 3.2
- Capping FPS via NVIDIA Control Panel to 97 (I read >120 can cause issues with NVSE on Nexus)
- Disabling all autosave features in game
- i9900k
- ROG MAXIMUS XI FORMULA (LGA1151)
- RTX 3090 FTW3
- G.SKILL Trident Z Royal Series 32GB (4 x 8GB)
- Samsung SSD 970 EVO Plus 1TB (install location)
