locked V2.2.2 stops working

Lars Berg

Working perfect for some hours, then  WSJTX stops with the this error. The only way I have found start WSJTx again is to make a  computer restart.
Using an IC-7100, W10 PRO 2004 , Fujitsi lunchbox, 2.9GHz, 16GB. SiliconLabs drivers
This happens one or twice times a day.
Any hint of what going wrong.
