Mouse Cursor Freezes Intermittently

Hello,I'm having an issue where my mouse cursor freezes intermittently when moving it, which gets really frustrating.I recently replaced my dead i7-4790K CPU (and Z87 motherboard) with a Ryzen 5 3600 (and MSI B450 Gaming Plus Max motherboard) - GTX 780, Catalina 10.15.7 installed via USB several months ago, and consequently switched from CLOVER to OpenCore (already did so on my laptop). That's when this issue started.

The mouse works perfectly fine in Windows, and in macOS Recovery. I've tried to plug it into different ports, same issue.

When looking at IORegistryExplorer, the mouse only appears once and continues to appear once when the cursor freezes (rather than appearing multiple times, as if power to the mouse cuts off and disconnects), so the mouse remains connected: likely a software issue.

Activity monitor shows no significant CPU activity, so lag can be ruled out. In fact, it's working fine in macOS Recovery.

Maybe I forgot to remove kexts from the CLOVER era? I already cleared NVRAM, and I included kext lists of /L/E/ and /S/L/E/ in case I forgot to remove any kexts that shouldn't belong there.

Here's my OC folder: https://gofile.io/d/Fl4FBG

Any help would be appreciated!

Thanks,
