Steps to reproduce the problem:
1. Create profile 1
2. Switch to profile 1
3. Close default profile (profile with folder 'Default').
4. Close browser and open again.
5. Browser has only 1 active profile. It is 'profile 1'
6. Open any webpage and open dev tools on that page.
7. Get assert because DevTools tries to load 'Default' profile from UI thread.
