Lift and Drag are not calculated

I’ve been trying to analyze this airfoil with a round trailing edge, but everytime I go into the Airfoil Analysis Module it shows nothing after analysis, not sure what is going on. I’m attaching the screenshots and the airfoil file, if anyone can help me I would be so thankful.

it seems that the trailing edge of your airfoil is closed. XFoil required a trailing edge gap.
Try to remove a few points at the trailing edge so that it is open. I also would not recommend simulating a rounded trailing edge in XFoil.
