Not sure you’re going to find a PC looper quite as good as Quantiloop.
You might have checked out this link Looper Software - an Alternative to Hardware?. Although Mobius does not appear to have been updated, it might work on your PC.
I tried Mobius on the Mac and found it a little too wonky. Decided to go the hardware looper route instead.
You also might be able to run QL in a virtual macOS session on your PC.
Let us know what you end up with and how it works for you.
