3ds max shortcuts were disabled when VFB was open (to make the VFB shortcuts work, which were not as crucial as 3ds Max shortcuts) in RC stage, but got enabled back for the final release.
In your other post (CoronaColorCorrect) I saw you were using RC1, not the final release. If this is still the case, please update to the official Corona 12.
Everything works as expected with Corona 12, just tested with 3ds Max 2024 and 2025.
