E_ERROR – caused in line 881

I have a problem that occurs completely randomly without doing anything.
The error is:

An error of type E_ERROR was caused in line 881 in the file / home / 5 / d / datavett / www / wp-cont ent / plugins / rselements / widgets /services/rs-service-grid.php. Error Message: Uncaught Error: Class 'Elementor \ Scheme_Typography' not found in / home / 5 / d / datavett / www / wp-cont ent / plugins / rselements / widgets /services/rs-service-grid.php: 881
