(Suspected) OpenCore Preventing rEFInd from Booting When USB is Plugged in

I have a triple-boot setup on my late 2013 MacBook Pro (Arch Linux, macOS Sequoia (via OCLP) and Kali Linux). I use rEFInd as my boot manager. (rEFInd -> OC -> macOS/ rEFInd -> GRUB -> Linux) Before I installed macOS/OpenCore, my rEFInd menu worked just fine when booted with a USB inserted but now it's just a black screen. GRUB and OC works when booted via boot priority but when rEFInd is the boot priority it is just a black screen. Could this be a setting in my config.plist? Again, this worked before OpenCore/macOS was installed. Cleared NVRAM, tinkered with some settings but still nothing.

Thanks lots.
