An odd ABS problem

[RHahn57]

Got back from a 2300 mile run up to Maine and back on/off road (2016 R1200GS) with an ABS fault. Dug at the 911 and it reports 0x480A05 on the front. Went ahead and bled down the brakes and cycled the pump through 911 diags. Went out the next morning to check it over and the front brake lever no longer compresses. If I crack the brake line at the lever it moves fine so the pump is not letting any flow through the front system. I confirmed this by cracking both caliper bleed screws and well and still cannot compress the front brake lever. Anyone seen this condition??
