I will explain that in more detail. I have a fresh install of Windows 10, Steam, MO2, and Skyrim. All mods are newly downloaded from Nexus yesterday and installed with MO2. I installed 2 mods by hand. SKSE64, SS hairs 350 and SS Hairs 256(Both of these are no longer available on Nexus). All settings have been followed according the installation video on Youtube posted by the team here. After 4 hours of instant game crashes starting Skyrim SE with MO2, I 1st found that Racemenu would not work with MO2. Once I disabled it, Skyrim would run with all other mods installed. But, I was getting issues with FNIS once Skyrim started. I told me that the MO2 did not have permissions to write to the mods folder. And also, I kept getting a message that stated that MO2 did not have permission to do the current command. I changed the permissions and the issue went away. No settings were wrong, and all installations were done correctly.
