I am encountering an issue in Mathematica where it's not recognizing a file in a directory. The file definitely exists in this directory, and when I move the entire folder to a desktop directory to shorten the directory path, it starts working. However, this workaround is inconvenient for my workflow.

I suspect the problem might be related to long directory and file names, a known issue in Windows. I have already enabled the "LongPathsEnabled" registry key, but it doesn't seem to fix the problem. Both my Windows 11 and Mathematica are updated to the latest versions.

Has anyone else encountered this issue, and are there any known solutions or workarounds to force Mathematica to work with long directory paths on Windows 11?
