mpv-install.bat: script seems to skip many extensions when mpv_args is not blank

[Canowyrms]

I modify the install script to add the args I want. I run the script as admin as per usual. This is the complete output:

Adding ".gbs" file type
Adding ".gym" file type
Adding ".hes" file type
Adding ".kss" file type
Adding ".nsf" file type
Adding ".nsfe" file type
Adding ".sap" file type
Adding ".spc" file type
The system cannot find the batch label specified - add_type
Adding ".vgz" file type
Adding ".m3u" file type
Adding ".pls" file type
Adding ".cue" file type

Installed successfully! You can now configure mpv's file associations in the
Default Programs control panel.

Press any key to open the Default Programs control panel . . .

Args I'm trying to add: --input-ipc-server=mpvpipe --no-ytdl (i.e. the full line is: set mpv_args=--input-ipc-server=mpvpipe --no-ytdl)

When I run the script in its original state, i.e. mpv_args is set to nothing, the script runs perfectly fine, no issues. Oddly enough, I did the same thing in a Windows Sandbox. The script runs to completion with args set. I'm baffled why the script "breaks" in my host OS but not in the sandbox.

Windows 10, if that makes any difference. Anything I should do differently? Anything I can provide to troubleshoot?

Thanks

False alarm, I guess.

It seems if I use VS Code (which may be doing something to the line-endings? I do prefer Linux line-endings) to add the arguments, the install script will fail.

Modifying a fresh copy of the install script (i.e. freshly extracted from a release zip) with Notepad instead, the script seems to run to completion as expected. Choice of editor was really the only difference between what I did on my host OS and in the sandbox.

I dunno. It did what I wanted it to do.
