Hi! If I click continue button when I see the error message, Manager will open blank. Please see below: [pic6]

I think I am having the same issue. Here is the error message I get: [image] If I click Continue I get the same blank window that @winner shows. If I click Quit and try to open Manager again, it seems that in about one in four or five times it opens with no problem. This happened with 20.10.81 an…

Update to Windows 10 20H2 - the latest version of Windows 10. Also look and see what version of .net you are running. I don’t think the version of windows is the problem.

The 20H2 update may only show after you have installed the update you are about to install. Or your computer may not be ready for the the 20H2 update, in which case I would wait. However, this suggestion will not fix your problem with Manager. I am just suggesting installing 20H2 as it fixes various…
