I have encountered this error : DxDiag says “DxDiag has detected that there may have been a problem accessing DirectShow the last time this program was used. Would you like to bypass DirectShow this time?”
If I click ‘Yes’ DxDiag appears to run normally. If I click ‘No’ DirectX Diagnostic Tool crashes.

What could be the cause? Any solution? Anyone else has encountered it?

I have installed Windows 10 Edu more than 10 times on my laptop..... I am frustrated now!.....

I have attached the dxdiag log file.
