I temporarily solved this by changing the names of the files in the /etc/gl-reset-network.d folder by adding a ! and made them permissions 0644. It seems that this solved my problem and after a reboot the configuration files /etc/config/network remain unchanged. I don’t know what these actions affected, but everything looks normal. If anyone knows what exactly these files are responsible for and why they interfered with normal operation, I would be very grateful and I hope this will help someone like me
