You can't have overlaps between obsm1 and metal1. You'll have to fix the layout.
If can open the gds in magic, I believe you can find the overlaps by executing the box commands in the console. Ex.

box 235198 339952 236125 340048
Can you find the problem?

@Mitch Bailey thanks for the hint. I am not familiar with magic tool for finding and fix the problem. If you've steps plz share will try at my end.
Also this is MPW1 shuttle design. Maybe re-harden with latest OpenLane may fix this issue.

To change the coordinates to klayout (um), divide by 200. In klayout, Display->Goto position will place a marker at the specified coordinates.
