As of July 2nd, again I can't start chromium after having rebooted Ubuntu without having quitted chromium first. This time, the error indicates a lack of removal of temporary symlinks named SingletonLock and related Singleton*. E.g.:
```

Upon removing of the 3 symlinks within the profile folder, still an error:
