Hi shifter141,
Thank you for the donation.
If the oil filter is dry, either there is no engine oil in the sump, the oil pump is bad or the oil strainer is clogged.
Hope you have not damaged the engine with the running.
If the oil level is correct, then I woud suggest removing the oil sump to check the strainer first.
Some owners likes to add additives ( oil treatment) to the engine oil and over time, a thick layer of sludge sticks to the sides/walls of the internal part of the engine. When the engine is left idle for a long time, these sludges dries up and the nextme the engine is started, these dried up sludges would collapse in bulk and when this occurs, trhey would clog up oil lines or the strainer.
When oil does not get to the top of the engine, the pistons would be dry and this results in the compression droppping which could be the reason why you are not able to start then engine.
