I got this exception when launching a compiled script (clicked on the script on the sidebar). Didn't have issue with launching the same script earlier. Build 38. I had Visual Studio debugger attached - not sure if that was a factor here. I re-launched WL again and the script is launching normally - no issues. So this exception was only one time - not sure if it is worth your time to investigate it. But just posting here as a data point to improve the product in case it rings a bell.

System.NullReferenceException: Object reference not set to an instance of an object.

There must be a breaking change in the WL7 API which got fixed by recompilation.

P.S. It usually happens like this: https://www.wealth-lab.com/Discussion/WL7-refuses-to-load-a-compiled-strategy-7196
