Skyrim SKSE Memory Error (The instruction at X referenced memory at Y)

When I launch Skyrim through the Skyrim Script Extender loader, I get this message:
"The instruction at 0x######## referenced memory at 0x00000004. The memory could not be read.

Click on OK to terminate the program."

But, when I launch it through the regular launcher, it's fine.

Why am I getting this?
How can I fix it?
Can I even fix it?

What's been done:
Opt out of Steam Beta
Run SKSE as an administrator
Re-install SKSE
Install SKSE beta
