I see some supports without anything attached–specifically under the arches. Was the arch base closed?
Unfortunately, I now suspect the issue is more likely the thin material folding during peels-and resets. This leaves you with ~4 options: 1) print directly off the build plate, 2) add a significant number of supports and/or print a thicker first layer(s) (e.g. 100um); 3) change the orientation of the model to a more stable configuration; or 4) try to optimize the peel to protect the fragile first layer. Unfortunately, I also think that this model might benefit from using PDMS instead of FEP.
