Repeated error message . . .

[AlanD3]

For many months I have been receiving an error message which reads "
An unhandled exception of type 'System.NullReferenceException' occurred in Toolbox Common. Crash report saved in Prltoolbox.3.6.0.1916.2020-07-25-12512-448.crash"

I kept hoping it would go away with updates etc. It has not.

It is displayed whenever I startup. I am running Windows 10 Pro (64 bit) within Parallels and Mac OS 10.15.7 (Catalina). Earlier version of Mac OS generated same message.

Each time I close the window and proceed. It does not appear to have any effect on proper functioning of my applications, utilities etc.

In the past when I have encountered "odd" problems the cause of the problem has been ascertained to a number of security, anti-malware, etc. programs that I run with both Mac and Windows and the VPN tunnel which I use religiously. Any thoughts/suggestions that can be implemented by a relatively unskilled person would be appreciated.

I started work on this effort yesterday with following the suggestion of downloading and using the latest version of Parallels Toolbox.
Multiple times (and today after a complete shutdown and restart this morning) I start the process of installing the toolbox, it copies varies files and then it
displays a splashscreen which says, inter alia, that "Please wait while the Setup Wizard installs Paralels Toolbox." The status bar turns green and extends to the far right hand side. It then stays that way (with the "progress" bar fully to the right) until I manually cancel it. Yesterday, during one exercise that was several hours.

When the same thing happened this morning I decided to go to the "Problem Reports" folder as advised above. All efforts to "upload a file" (compressed or not) or even subfolders/files was met by an error message of "too large." I tried copying and pasting the toolbox.log below hoping that might be of some benefit but that generated a message saying message needed to be shortened.

The "Setup Wizard" continues to be in the same display as it was more than 15 minutes ago as of when I post this reply.
