Description
I am using Windows 10 with CUDA 11.8, Python 3.10 and ctranslate2 4.4.0.
The problem already seems to reported in the faster-whisper repo but I also have it when I directly use ctranslate2:
https://github.com/SYSTRAN/faster-whisper/issues/71
The python process crashes after executing this code:
import ctranslate2
model = ctranslate2.models.Whisper("openai/whisper-tiny", device="cuda")
It is not the the code itself that crashes the process but I guess some kind of internal routine on process exit that is necessary for CUDA.

Research direction
Start by reproducing the crash with the shown ctranslate2.models.Whisper example on Windows 10 with CUDA 11.8 and Python 3.10, then compare the behavior with the linked faster-whisper issue. Done means the Python process exits normally after creating the CUDA-backed model, with the relevant exit-time behavior covered by a regression test.
