Quake had it’s own vm also

There is one in golang regular expressions https://swtch.com/~rsc/regexp/regexp2.html

I guess that is why you say re.Compile.

RarVM was used in a previous version of the format, newest RAR has removed it, and RarV5 doesn't have a VM.

This list is entirely incomplete without mentioning Java Card.

There is a tiny Java Bytecode VM in an insanely large list of places, you can find some of them here:

TikTok shipping XOR cipher'd bytecode & interp is right up there: https://news.ycombinator.com/item?id=34109771

yt-dlp's jsinterp.py

I've got subleq+eforth (https://github.com/howerj/muxleq) running in JS which is dead simple to do. No input but I could output ASCII mapping values to an array.

So, yes. yt-dlp runs propietary Youtube JS code defying the original purpose.
