Trouble compiling Aseprite - Python tools access

Hi, I keep getting an error message when I enter the “python tools/git-sync-deps” command.

The error message is:

remote: PERMISSION_DENIED: The caller does not have permission
remote: [type.googleapis.com/google.rpc.RequestInfo]
remote: request_id: "9938758fe958471b82471f0e8d3aee32"
fatal: unable to access 'https://skia.googlesource.com/third_party/libjpeg-turbo.git/': The requested URL returned error: 403

Has anyone had this issue? I can’t find anything online. Thank you so much!
