Error 500

[slazzy98]

I have updated today module called  "tips and upgrades" by prestashop, I did never install this module so I assume it comes preinstalled. 
Right after the update I got an error 500. Gone to FTP and turned on the debug mode - everything works fine, backoffice works, front works, everything is perfect, I gone ahead and turn off the faulty module, debug off, error 500. Then I have tried also uninstaling the module, still error 500.
At the very end I did try clearing all cache manually, and now the backoffice works perfectly when the debug mode is OFF, as soon as I turn the debug mode I get this error:

 

(1/1) FatalErrorException

Compile Error: Container3cxb0nm\appDevDebugProjectContainer::load(): Failed opening required '/home/rhbfokv/www/escooterclinic2/var/cache/dev/Container3cxb0nm/getAnnotations_CacheService.php' (include_path='/home/rhbfokv/www/escooterclinic2/vendor/pear/pear_exception:/home/rhbfokv/www/escooterclinic2/vendor/pear/console_getopt:/home/rhbfokv/www/escooterclinic2/vendor/pear/pear-core-minimal/src:/home/rhbfokv/www/escooterclinic2/vendor/pear/archive_tar:.:/usr/local/php7.2/lib/php')

in appDevDebugProjectContainer.php line 1768

Anyone had similiar issues with update of this module or with debug mode?
Thank you for your help in advance.
