After upgrading to 2018.1 I have been getting an error every time when searching for a variable type. It gives an error when typing the first letter, then the same error again when typing a second letter. After that, the error no longer occurs. All functionality remains, it’s just a pain having to click “OK” twice every time I need to search for a variable type. It looks like an assembly file is missing after the upgrade, but I’m not sure how to diagnose or fix. Any ideas?
