Summary
So far, we think the issue is a combination of Windows not having paths longer than 260 characters enabled by default, but is possible to fix on Windows 10. On Windows 10, after doing the registry fix (and rebooting?), you must enable core.longpaths in Git for Windows and possibly other Git clients you may be using.

Solution
Step 1: Run Registry Modifier
Download and run this script to apply the fix –> Remove 260 Character Path Limit.reg
Reverting
If you need to go back for some reason, run this file:
Restore 260 Character Path Limit (Default).reg

Step 2: Set Git's core.longpaths = false
csa
In a terminal launched with Administrator mode.
Solution from: https://stackoverflow.com/questions/22575662/filename-too-long-in-git-for-windows
If USING CMDER, the config file is here instead: \path\to\cmder\vendor\git-for-windows\mingw32\etc
[core] longpaths = true
