White screen in gSender

gSender 1.4.11
Long Mill Mk1
SLB

Yesterday, while cutting the finishing toolpath on a .crv rotary file, the gSender screen went completely white. The job ran for another few hours to completion.
I am attaching the diagnostic file, but Iā€™m not sure if it will help at all since I had to shut down and re-start gSender to bring up the GUI screen
