Arnold 6.2.1.1 GPU Error Maya 2020 and Maya 2022

Hello, over the past week I've been experiencing this error message.

Error: [gpu] an error happened during rendering. OptiX error is: Unknown error (Details: Function "_rtContextLaunch2D" caught exception: Encountered a CUDA error: cudaDriver().CuEventSynchronize( m_event ) returned (700): Illegal address, file: <internal>, line: 0)
GPU 0 had 7253MB free before rendering started and 5743MB free when crash occurred

I have no idea how to solve the issue, Maya won't let me render using my GPU.
It will tell me to restart.
"Error: [gpu] Fatal GPU error occurred, please restart the host application".

To be clear, the CPU renders perfectly, this error message only appears occasionally when using GPU rendering.

I'm using the RTX 3080 graphics card, drivers and Arnold are all fully up to date.
I've tried using both Maya 2020 and 2022 and I will still get this error message.

This is basically a generic crash message:

Error: [gpu] an error happened during rendering. OptiX error is: Unknown error (Details: Function "_rtContextLaunch2D" caught exception: Encountered a CUDA error: cudaDriver().CuEventSynchronize( m_event ) returned (700): Illegal address, file: <internal>, line: 0)
GPU 0 had 7253MB free before rendering started and 5743MB free when crash occurred

It could be anything, a bug in Arnold, a bug in the graphics driver, a bug in Optix.

If the crash happens only sometimes, then it will be harder to troubleshoot. Normally, we try to isolate the problem: is it textures? shading? some scene element?

The version of Maya probably doesn't matter, because it's the same version of Arnold in each Maya.
