Your video shows 210° which is way to cold for ABS. If you did no cold pull when switching from ABS to PLA there are remainders of ABS which will not even melt.

Oh yes!
But what of the ABS is still there in the hotend and nozzle will not melt at that temperature and is causing your clogged nozzle!
Anyhow I seem to remember that a mixture of PLA and ABS could even react unpredictable.
Thats why I recommended a coldpull which at least provides a nozzle without residues of previous used material.
3D-print basic knowledge I dare say....

basic knowledge 😀 I am printing about one year switching ABS and PLA with no problem. I always put every last piece of ABS before changing the temperature. Anyway as I said before the extruder doesn't want to take even ABS even with higher temperature (270°C)
