Error Missing Connection Between items,but all are connected

I am using Kicad 9. When I am running my DRC below error is obtained.

My complete layout is given below.

When I click on the error entire pcb is getting highlighted and it is not showing any markers.

The zoomed version of PCB is given below.May I know what I am missing.

It’s the “obvious”. I’ll cut out a small section of one of your screenshots to make it clear that this section of the +3.3V net is an isolated island and not connected to the rest of the same net:

This is often overlooked by beginners which don’t know what to look for.

And isn’t made any easier by the ambiguous message. I have suggested that the message should say “the net is split in several parts” or something like that.
