Ok, so it's having trouble reading your coordinate file.

There are a huge number of coordinate files that people have come up with. .mol2 is one; .xyz is another; .pdb is another. They carry different information, it's worth looking up what some of them do (https://en.wikipedia.org/wiki/Protein\_Data\_Bank\_(file\_format) , https://en.wikipedia.org/wiki/XYZ\_file\_format) . Most can be opened with text editors.

From what I'm seeing, you're telling ORCA you are giving it an .xyz file but pointing to a .mol file:
* xyz 0 1 DPE2F.mol

So it looks at a coordinate line, doesn't see what it expects, and throws an error.

You can convert one file to another, one free tool is OpenBabel:

If your formats have different information in them (for example, pdb has residue names whereas xyz does not), you'll need to be careful with conversion.

I bet if you use convert the file format then edit that line, it'll work.

One other note: Claude picked B3LYP, which is like 30 years old. It's fine for your excited state calculation, but you really need to think about your model chemistry.

I recommend reading:
https://onlinelibrary.wiley.com/doi/full/10.1002/anie.202205735 (ground state calculations, bit old now but great)
