Nvidia Encoder Error

**FastFlix Version:**
6.2.1 Windows x64

**Operating System:**
Win 11 25H2

**Describe the bug**
Nvidia Encoder errors out during batch process
AV1 Rigaya NvEnc encode, 2 pass, lookahead 32, 3000 Kbps, 10-bit.
GPU load never exceeds 4%, fan never powers up because it is a mild 45C

When the error pops up, the CLI screen closes. When I close FF in this state, sometimes FF crashes. There isn't much useful info in the logs.
