Modern Interface Not Working After Update from 5.5 to 6.2

Hello Traccar Community,

I recently updated my Traccar server from version 5.5 to 6.2. After the update, I am unable to use the modern interface. The classic interface works fine, but when I try to access the modern interface, it fails to load.

I can see now that I have posted in the wrong forum... sorry!
