Since a few days ago, I have started getting an error when the extension has to deliver the Function Call Trace. The error is as shown in the picture:
This happens always, regardless of the contract/function I try to run it on. I am using this extension on VSC, Windows 10. Anyway, since the error message requests the code to be posted, here is an example:
