Why did you tell them about your "government job"??? That blows my mind why you would reveal that. You brought this on yourself. You should have just gone with soft power. Jesus.
Usually applications are cancelled for technical reasons, like incorrect information or failure to provide requested documents. Regardless, they don't have to tell you the reason. It's not the same as having your application being rejected, which would mean you're ineligible for the visa. So, you can try again but I recommend a different embassy.
I wouldn't worry about as it doesn't actually change anything. You would still have to get a new passport well before December 2029. Likely 6 months before.
