Creality Ender 3v3: Making a strange noise

Hi everyone,
I am on this forum again because I had recently experience a new issue with my Creality Ender 3v3 printer. I was printing fine just a few days again and then just yesterday I heard a strange noise coming from the printer when I was getting ready to swap out the filament color. I had previously ran out of a color and went to change it but this happened instead.

The thing(s) I did to diagnose my problem was taking apart the hotend assembly to discover this.

The white round piece in this photo is where I can’t seem to get my tool to go through to unclog it. I did just replace the entire nozzle not too long ago. Probably in the last couple weeks of using it.

Thanks in advance for all your help in fixing my issue.
