Interception tools / dual function keys and current mainline kernel

I have a been using a set-up for years, I tap control or alt it emits a key combo and I configure this combo to run a script or program.

This runs fine on all kernels, but 6.10.n, where it runs intermittently, some boots it fails, some boots it works. I am currently having to run LTS, to get it to work. Can post more when I get home (at work, forgot to pack my tablet!). I am seeing this on more than one computer.

Anyone else use interception tools?
