Gray tank plugged, limited options
Yes, I know it's been beaten to death but please bare with me. 70, disabled, on SS so on a budget. Not the issue, just sayin'. Yes, I'd love to have Joes RV Specialist come out but I need to try some...

I also think the valve isn't opening. Need to access the valve to inspect it (and cable) which unfortunately isn't going to be fun. Ignore the tank readings as they are notorious for being incorrect due to sludge buildup on the sensors.
Another idea might be to add a cleanout in the 1-1/2" ABS pipe coming out of the grey tank if you have clear access to the pipe from below the underbelly. Could use "Fernco" fittings to insert a wye into the pipe if needed. Then use a snake to clear the blockage. But this isn't going to help much if the problem is the valve not opening.
Are you away on a road trip or near home? You could try finding an independent RV repair shop and plead your case and see if they can help you out for no charge.
When you do have it back to normal again, I'd suggest using a cleaning product to thoroughly clean all 3 tanks. Liquid Drano works great and won't hurt plastic or metal. There are others plus the "geo method". Need to drive around though to get it to slosh around.
