Hi Mikhail,

It looks like the crashes are occurring due to a NullReferenceException in code that is part of the project. When I observed this in the past, I found that I needed to add a check to the constructor of my forms and/or controls to prevent them from running code that requires application state not available in the debugger. The LicenseManager.UsageMode property provides the information necessary to check this condition, which might look like the following:

if (LicenseManager.UsageMode != LicenseUsageMode.Designtime) {
  // Run code that cannot run in the designer
}

I haven't looked at the specific source files to determine the exact place where this check would need to be added. Please let me know if you get stuck and I can look into it further.

Thank you,

Sam Harwell
