Usually with Linux software, a new complete version install over an older version, could brake something, if they are offering update packages.
So, I would try using the update package.
Here is the downloads for the update package.
https://code.visualstudio.com/updates/v1_65
The Linux deb package should work in Fossapup64 9.5
https://update.code.visualstudio.com/1. ... x64/stable
Note:
With Puppy Linux, best to download the deb package.
Left mouse click on it to install.
I looked in their FAQ about updating and it seems the update package will just update the version that is already there.
They say nothing about the update doing anything but update.
Not in Fossapup64 right now, but this may also work.
Could look in the Puppy Package Manager(PPM)
Make sure to first run PPM -> Configure -> data base update
Do a search for visualstudio or vscode.
If it finds anything.
See if it is finding this v1-65 update.
If yes.
PPM should be able to install the update.
The things you do not tell us, are usually the clue to fixing the problem.

This is not what I expected
