Does it work if you remove the behavior and then re-add it? Maybe it's some random bug.
Do you have other objects with MoveTo behavior?
Are you using any addons? It's possible that some of the addons is somehow clashing with MoveTo plugin.
1. I’ve tried removing and re-adding it, but it’s still not working.
2. Only one object has the MoveTo behavior.
3. I have no browser addons, and I even removed Chrome’s default extensions.
4. And for Construct 3 Addons, I only use the usual ones in the project (Audio, Browser, Keyboard, Mouse, Platform Info, Touch)
5. Installed addons also not much
