Meshroom process doesn't start -FileNotFoundError: [Errno 2] No such file or directory

[ChrisM2017]

My computer previously ran meshroom perfectly well, but now seems unable to run the process. I open the program, save the file to the required folder, and load some images. When I hit start, however, nothing happens, and the file not found error message appears in the log (example copied below).
A clear and concise description of what the problem is.

If applicable, add screenshots to help explain your problem.

If applicable, add a link or few images to help better understand where the problem may come from.

This makes it impossible to correctly group the images by device if you have used multiple identical (same model) camera devices.
The reconstruction will assume that only one device has been used, so if 2 images share the same focal length approximation they will share the same internal camera parameters.

If applicable, copy paste the relevant log output (please embed the text in a markdown code tag "```" )

Desktop (please complete the following and other pertinent information):

• OS: Windows 11 pro
• Python version (not sure)
• Qt/PySide version (again not sure)
• Meshroom version: 2023.3.0 - just downloaded the standard version - I certainly haven't 'built' anything
  • Binary version (if applicable) (not sure)
  • Commit reference (if applicable) (not sure)

You'll probably gather from the above information that I'm certainly not an advanced user, but I would very much like to be able to use the application again. As far as I am aware, the associated programs (windows visual C++ and Nvidia drivers etc.) are up to date)

Any suggestions for a solution would be gratefully received.
Add any other context about the problem here.

That's strange. Storage full? Project path too long?..

[ChrisM2017]

Thanks for the direction, Fabian. I shortened the project path and everything worked again as normal. Thanks again for your time.
