Nozzle stuck in heaterblock

A few days ago my nozzle clogged AGAIN…! I have disconnected the isolator guide from the nozzle an now i want to get the nozzle out of the block but is stuck solid. i cant get it out.
All the time the filament is getting stuck somewhere in the nozzle. I want to clean it but i have to get it out of the heating block first. Any idea’s?

I have used a heat gun to make it hot.
Do not force it as it may break
