Could you please save your system information (Help > Save System Info) and attach the file to your report? Has this previously worked on your system and if yes, have you installed a new graphics driver or OS update before it stopped working? Does it work in a previous version of Blender, e.g. 2.91.0?
Thanks .yes i have same error on the other blender versions too. it seems to created newly . cuda worked very well previously.
system-info.txt
Blender detects the GPU but there is an error initializing CUDA.
Please open Blender's installation directory and double click on the
blender_debug_gpu.cmd. This will start Blender in debug mode and create log files. Once Blender is started, open the preferences and try to select CUDA again. Once this fails to work, close Blender. The Windows Explorer should open and show you up to two files, a debug log and the system information. Add them to your bug report by clicking on the upload button as shown in the screenshot below or via drag and drop.It shows up error again.
blender_debug_output.txt
blender_system_info.txt
Unfortunately the debug log doesn't contain additional information. Please uninstall and reinstall the graphics driver for the GPU. If this doesn't resolve the problem, repeat this but use an earlier versions of the driver .
Ok . thank you
After uninstalling latest driver and install older version. every things came back.
That's good to hear. So the 460.89 doesn't work for you at all? What is the current driver version that works properly?
Now i use 430.86
latest version has cuda detection issue .

Thank you for letting us know. I'll inform the other triagers that there may be problem with that specific driver version. Since the issue appears to be in the graphics driver and not in Blender, I'm closing this ticket.
@newsoft Is the 430.86 the most recent version that works properly or did you pick this specific one for a different reason?
No that was just an older download file.
Thank you too for your response.
