Access Violation errors

Any experts on troubleshooting access violation errors? This has been driving me slowly crazy for a few months now and is happening on both Sonar Pro and also the new Bandlab Cakewalk.

I don't get it every time but most commonly if I save a project and then quit Sonar I often get an access violation error (0xc0000005). If that was the only time it happened I could live with it but a few times it's also just happened randomly when I'm working in the middle of a project out of nowhere. I've saved the minidump files each time and when I use osronline.com to analyze the .dmp files they all seem pretty similar to this example:

I'm no coding expert but I guess it points to a clash between WMVCORE and MelodyneReWireDevice.dll so I did some searching and WMVCORE seems to be related to Windows Media Player. I removed that from my system but still get the errors referring to it. I also tried reinstalling Melodyne but again no good.

I've run memtest multiple times to check my RAM and that all seems fine. I've gone through checking/updating video drivers and everything else I can find but it keeps happening.

I guess it must be specific to my system as I can't see many other people with this problem. Any other ideas what to try? I can provide the full dmp files if they'll give any answers?

Win 10 (64 bit)
Scarlett 8i6
8GB RAM

Thanks for the suggestion, done that already though as well as everything else obvious I can think of. Avast is running permanently and I've double checked with Malwarebytes.

It's a fairly clean Win 10 install with not much on it apart from my main audio apps and a couple of image/video apps (GIMP/Vegas and a few others). I certainly steer clear of dodgy sites and unknown sources.
