The new Micro~~soft~~slop copilot key always sends the following key-sequence when pressed:
copilot key down: left-shift-down left-meta-down f23-down f23-up left-meta-up left-shift-up
copilot key up: <null>
This means there's no real key-up event when you release the key --> it can't be used (properly) as a modifier like ctrl or alt.
The workaround is to send a pretend key-up event after a time delay, but then you mustn't be too slow / fast when pressing a shortcut.

- Windows workaround https://github.com/randyrants/sharpkeys/issues/560

tldr: AI took a perfectly working modifier key from you.
--- edit ---
Some keyboards apparently do the "right" thing and don't send the whole sequence at once, you can remap those properly with keyd, see: https://github.com/rvaiya/keyd/issues/1025#issuecomment-2971556563 / https://github.com/rvaiya/keyd/issues/825
copilot key down: left-shift-down left-meta-down f23-down
copilot key up: f23-up left-meta-up left-shift-up
this will still break left-shift + remapped copilot and left-meta + remapped copilot, but RCtrl remaps should work as expected
VM the program? I know that seting up a Apple VM is nothing easy but that will allow you to just use you preferred OS and run that program in the VM. I use winboat on my Pop_OS! laptop for some software that really needs Windows and does not work well (at all) in wine. I dislike the we know better that you mentality that comes with buying a Mac. Hell the amount of times the update fubar'ed my system because Apple decided to update software that has nothing to do with the OS is too damn high.
