Can I exit the country without issues if my visa is not stamped in my passport anymore?

Welcome

Considering that you have a case and there is no travel ban because of it, and your passport is in your possession, you can travel and follow the case from outside the Emirates.

If your question is other than this, please explain.

Please send a copy of your Emirates ID via WhatsApp to check your status from the general public order at the Ministry of Interior and confirm your current status inside the United Arab Emirates.
