Cura 5.0 works fine, 5.1 disables extruder

[ADmakes 0]

 Cura 5.1 is somehow disabling my extruder.

When I bring a model into 5.1 and slice it, the result is always 0 grams of filament. The print head moves through all the code, but nothing is extruded. I'm using filament and print profiles that were working in 5.0. 

Cura 5.0 works fine with the same models. 

I copied my start and end code from 5.0 to 5.1, and it will print the prime line and the skirt, then stops extruding. This is not a clogged nozzle or anything physical/mechanical. 

Im running Klipper on and Ender5.

 

Any ideas what to check? Its something with the extruder instructions

Save a project and share it here, and we can see what is going on.

ok thanks.  here is a saved project and  a screenshot. As you can see 0g of filament and 0.02 minute print time.

I rebooted my computer and it prints normally now.
