**Steps to reproduce**
1. open project
2. a red exclamation mark appears in the corner

I believe I have this fixed, but haven't been able to reproduce it. Can you see if this solves the problem?

For my project, it happens consistently:

1. start rider (i have the project selection window)
2. select project
3. look into the bottom right corner, and there is a red error exclamation mark

3/3 tries this thrown on 1.6.2

On 1.6.3 it no longer happens. Formatting still works, so all good from my testing
