problem with auto-sandbox?

I used to play DiRT Rally (on Steam), but when I tried to run it a few minutes ago, the game crashed silently.
When I looked into Comodo’s Task Manager, it would appear with “virtualized” next to it, then crashes.
I disabled auto-sandbox, then the game would start correctly without displaying the popup “should it be sandboxed?”.
It was also crashing another game started from the Oculus store.
Was there an update recently?
