What explains the failure of the blitzkrieg of Nazi Germany against the USSR?

The failure of this concept of warfare was due to the forced retreat from it. The territory of the USSR was huge. Even the capture of Moscow did not give a 100th guarantee of victory in the war. Many scientists claim that Germany has not received any enterprises as trophies. This is not true. The authorities of the USSR did not always manage to evacuate enterprises in a timely manner. This applies to lands that were in close proximity to the western border of the Soviet Union. Moreover, the Germans owned technologies that were much more progressive than the Soviet ones and almost all of Western Europe worked on them. The problem for Germany was the partisan movement in the rear. German troops stretched significantly across the occupied territories and were forced to constantly suppress partisan units. The siege of Leningrad weakened the power of the troops in other directions. The Germans are not used to fighting in the cold winter conditions. The war in North Africa made it impossible to strengthen the Eastern direction. Lend-Lease allowed the USSR to hold out and go over to offensive actions.
