Description

Hello everyone, I have encountered a strange problem and would like to ask for your help.

I have a project on an SMB volume (both the volume host and the mount end are Windows), in which some modules depend on others, so after using npm i to install the dependencies, there will be some directory links.

When I run my node program, some linked modules cannot be loaded and report the following error:
Error: EINVAL: invalid argument, readlink '/path/to/module', but this path dose exist and is accessible. I can navigate to the module directory by explorer.exe. After I access it from explorer, I start my program again, and at this time, the program can load this module normally, but the same situation will occur with other linked modules afterwards (just some of the linked modules). I can repeat the above steps until all modules are loaded by not modifying anything.

I'm not sure if this is a bug in the fs module or Windows, I have not encountered similar errors caused by SMB directory links in other programs before. I hope someone can help me analyze this strange phenomenon.
