Must have been too low of oil, 1 quart was not enough unless it brought the oil level up to the line on stick. Otherwise oil pump may have went out.

Have you tried to turn motor over by hand at crank, if it will turn over then it may be something else. If it will not turn over by hand pull the spark plugs out and try to turn it over, if it will not turn over squirt some penetrating oil in each cylinder it may come loose (let it work on it a few days.

Also if you have an oil leak or just have not checked you oil, Try to check it more often.
