Reassembled nozzle w/o PTFE tube and printed, now very clogged. Best way to fix?

The title says it all.  I had partially disassembled ptfe tube fitting to the nozzle to try and fix an issue with poor extrusion, got distracted, and ended up walking away for a while.  Came back, and put the fitting back on without the PTFE tube and ran some test prints.  Printed great the first time.  Now, the inside of the nozzle is full of PLA.

Do I need to replace the entire hotend to fix this? Can I just replace the heatbreak/nozzle/heaterbreak?  Do a really aggressive cold pull?

Any help would be appreciated.

You can sure try to disassemble the hotend again and take a heat gun to it but honestly I'd put an order in for a new hotend.

That’s what I was afraid of. Are there specific guides for replacing the hotend or is the assembly manual the best way to go ?
