There was no Bronze Age collapse, apart from the arrival of forces armed with steel. Attributing something that happend in the 15th c BC (the Conquest) to an alleged event that happened in the 13th c BC never made any sense, anyway.

So there was a collapse. Interesting you assert one negative while also affirming the premise right after that.
Also recent scholarship agrees that there “was” a collapse.
