Lens studio scripting changes since 4.36.1?

I just noticed that a simple Blink detector script we built to simulate some eyelids opening via Tweens seems to have stopped working in 4.43. I can reliably open the project in 4.36.1 and have it work while opening the same file but on 4.43 leads to the script not being called at all…
I checked the changelogs but can’t really understand where the change would be coming from. Anyone else notice some broken scripts?
