Undefined constant "DS"

Undefined constant "DS"

After installing the JoomShopping component version 5.1.3 in Joomla 4.2.9. and Joomla 4.2.9. an error occurs in the administrative panel Undefined constant "DS". Returning to the control panel causes a crash.
The cache in the system has been cleared, a reboot has occurred. The error has not been eliminated. At the same time, the front part of a JoomShopping works well.

Could you possible fix it?
