Sound deterioration after 20 minutes playing

Good evening,
I’m using Audirvana since one year and had no problems (Windows 10 PC + DAC Audiophonics U-Sabre ES9023). Since the last update I have a distorted sound after 20 minutes playing, then it slows down and there is an echo. If I stop and start again the sound is correct, for 20 minutes… I tried my DAC with an other player and it works perfectly, I tried Audirvana without my DAC and the problem occurs the same way. I changed the USB port, increase the ram allocation, and it doesn’t change anything. So I believe it’s the last update, or a windows 10 update with compatibility issues ? Is there a new version coming soon to solve the problem ?
Thank you for your help.
