 Summary of the bug:
 I'm encountering a problem with the cuCtxDestroy function that seems to be
 causing my system to freeze and result in a black screen. I'm running
 Windows 11 on my computer, and I would appreciate any assistance in
 troubleshooting this issue.

 When I call cuCtxDestroy, it takes more than 10 seconds to complete,
 during which both the GPU and CPU appear to be stuck. Eventually, the
 screen goes black, and in some cases, the system may recover, while in
 other cases, it requires a system reboot.

 Here is some information about my system:
 * Integrated Intel graphics card
 * NVIDIA GeForce GTX 1650
 * Driver Version: 546.65
 * CUDA Version: 12.3
 * Windows 11
 How to reproduce:
 {{{
 Continuously create and destroy nvenc/cuvid codecs
 }}}
