    VS2019 parameter is not valid errors when opening previously created forms


    Running the latest version of VS2019 and when I try to open a form that was previously OK to open, I get something like this appear. Not all of the forms do this at the same time but occasionally all of them will eventually behave this way.

    If I click on the Go To Code link, everything looks correct and the variable that was supposed to be undeclared is OK. This happens randomly with various forms. Closing the solution and exiting VS and restarting allows the form to open but within a short time of working on the project, the same error appears.



    I can run the project with F5 and I can build a setup and it runs fine on the destination PC.



    I've searched around for this issue but so far unable to find a solution. It is slowing down the development as I am unable to open the forms to work on them.



    Any ideas?

    :)
