ORA-01666: controlfile is for a standby database - My DB Doesn't OPEN

Question

dear Gurus,
I've created a Standby, and Configured the Dataguard no issues.
I've start a swtchover into Site 2
After half an Hour without responding I cancle the operation.
Now I'm facing this Situation, My Standby Site still Ok but my Prod Database shows ORA-01666: controlfile is for a standby database
What shall i do?
When I check the Config in the Dataguard Broker everything seems ok for SITE 2
DGMGRL> show site verbose 'CFMP_SITE2';
