3D printing is broken in latest release

[blair0011]

I have 2 gcode files to print the same 3D object one made by version 4.10.2 which works and the other by 4.11.0 which does not extrude filament. The head moves but the code seems to back out the filament to a point where it doesn't touch the heated surface. I tested the nonworking file 3x and got the same failure. Went back to the old file and it is currently printing well. I did a comparison of the 2 files but the number of differences is too much for me to trace the issue too, also I am have not had enough time to explore Gcode programming so I am not sure what code change could have caused this problem.
