NV_ENC_ERR_INVALID_DEVICE Error

I was streaming a game when, at some point, abnormal lag started occurring in the game. After that, OBS encoding became overloaded, causing the stream to appear severely choppy. Eventually, the stream completely shuts down.
Sometimes, instead of shutting down completely, the stream alternates between appearing choppy and appearing normal.
I've attached the OBS logs and crash logs.
The error log I found contains an NV_ENC_ERR_INVALID_DEVICE error.
Please let me know if there's a solution.

Code: 
18:22:39.173: Device Remove/Reset!  Rebuilding all assets...
18:22:39.190: [obs-nvenc] get_encoded_packet: unmap failed: 4 (NV_ENC_ERR_INVALID_DEVICE): Device passed to the API is invalid.
Your graphics driver crashed and OBS wasn't able to continue.
This is usually a graphics driver or hardware error. Reinstall the graphics driver, but if the error persists it might be a hardware issue.
