Pimcore keep loading(error: Cannot find perspectives configuration)

I have been working perfectly on a skeleton version of pimcore when suddenly it just started to load and it wont stop. I did clear the cash and update composer but it is still the same. In the log files it shows that it cannot find perspectives configuration.

Is there any way that i can configure/update/generate these again ??

Hi,
perspectives file can be found under /app/config/pimcore/perspectives.php.
But this should be an optional file.
