Windows 10 .NET Runtime Event 1026 then followed by taskhostw.exe Application Error Event 1000

[DonT5]

I have filed several problem reports already about the taskhostw.exe Application Error Event 1000 which I have had no help and now just before I get the error I am now getting .NET Runtime Event 1026. I am not the only one that is getting these errors. This did not start happening until after my 5/30/19 v1903 update and the installation of KB4495620 Cumulative Update for .NET Framework 3.5 and 4.8 for Windows 10, version 1903 and June 11, 2019—KB4503293 (OS Build 18362.175) . This needs to be investigated by MS engineers and a fix deployed. I have run SFC, all three DISM's and no problems detected. I have also ran Malwarebytes scan, Norton full scan and malware scan and all are negative. I have also filed a problem report through the Feedback Hub.

Regards
