PLA floods hotend, MAXTEMP error, can't dissassemble

I am very new to 3D printing, so please take my comments below in that context.

I recently assembled and have been using the Prusa i3 MK2S with success on PLA prints. Today, I was printing an object (PLA), stepped away for 30 mins, and came back to see that print had broken free of bed. Somehow, the majority of PLA flow was diverted up and into the hotend housing and fan area (see two attached photos). Now I have several problems and looking for advice on how to proceed:
[1.] The MK2s now gives MAXTEMP error, so it wont let me heat up the hotend (there may be a short inside hotend assembly).
[2.] Since I can't heat the unit, I am not sure how to go about cleaning off all the PLA and trying to restore the hotend assembly to working order.
[3.] At least one plastic part of the Prusa MK2S on the extruder assembly has broken. So even if I can get the assembly apart, I can't print plastic replacement parts for them since the printer won't heat up.
[4.] With so much dried PLA around the hotend and the inability to heat the unit, I am not sure if I will be able to salvage the hotend at all - freeing it from the plastic tomb using pliers and cutters is probably going to irreparably damage the hotend (the melted PLA got right in between all the hotend wires - see photo)

Any thoughts on how to move forward and minimize costs of doing so would be most welcome.

Thank you in advance for your advice.
