Today I was editing an existing form and tried to add a WebMainMenu as usual. I added the WebMainMenu, and an item with two children. Ran the app fine.
When I tried to add a second item, I had the "It Looks like we are having issues" crash dialog. Tried many times, even exiting completely visual studio code and entering again and the same happens every time.
From the samples I opened the MainMenu sample and it fails there as well.
The Last time I added a main menu was about two months ago.
My currently version installed is TMS Webcore version: v2.0.5927
