Answer:
The major problem that George Washington helped stop just after the end of the American Revolution was the Newburgh Conspiracy.
The Newburgh Conspiracy occurred in 1783 when some officers in the Continental Army were disgruntled over unpaid wages and pensions promised by the Continental Congress. There was a fear that the officers might overthrow the newly formed government. George Washington played a crucial role in defusing the situation by addressing the officers and urging them to remain loyal to the government and by demonstrating his commitment to the principles of republican government and civilian control of the military. His actions helped prevent a potential military coup and reaffirmed the principle of civilian authority over the military in the new United States.
