Was there any single points in the timeline of the Western Roman empire that led to it's collapse or was it all just long-term factors?
Long term factors
Long term factors built up over the centuries in conjunction with individual points of stupidity.

Bad decisions early on lead to it.
Its not like a full roman empire collapsed overnight.
Empires survive by importing energy to get stuff done. When they run out of places to enslave, they can't maintain what they've made, and it collapses.
The West is unpredictable because we've never had quite as much energy as with fossil fuels.
