[BUG] npm -v errors with permission issues (npm 6.14.4, Node.js v14, Windows x86)

[kewde]

What / Why

Attempting to run npm -v errors with '-1073741819'. It is specific to this version, Node v14 on x64 & all previous Node V13 (x86 & x64) work fine. Sometimes it works fine, but if you loop it for a few iterations eventually it will error (I used 500 iterations)

When

• unknown timing, after installation, race condition occurs.

Where

• npm/cli

How

Current Behavior

Please note that for all other versions of Node & npm & distros (Linux / Windows) & arch (x86 / x64) my script runs perfectly fine.
