import data `.gpr` file error

[fengziren]

python --version
Python 3.10.4

The prompt I get when I run the software supports gpr files.
Can only read dt1, DT1, hd, HD, DZT, dat, GPRhdr, rad, rd3, rd7, and gpr files

The following error occurs when I import the .gpr file.
PS F:\study\GPRPy> gprpy
Profile [p] or Common Midpoint / WARR [c]? p
Exception in Tkinter callback

What should I do with it, please?

This is the file I imported and I can guarantee that the file is correct, this is what the file looks like when I open it using the software provided by 'esay radar usa'
