Translation in Studio not synced to cloud account

I'm using SDL Trados Studio 2021 SR1 - 

I’ve created a cloud project, but tonight I found the translation I did in Studio not synced to cloud anymore. My cloud ID sign in is fine and I can open the SDL Account from Studio, but the file in cloud just not updated. And when I save the traslation in Studio, there's alway a notice says my local version file is confilicts with the cloud version and asking me if to overwrite with the latest version (but which is not). 

I've tried reopen the Studio and restart my laptop, all didn't work. I really need help with this and thank you so very much.
