Problem happens with a file of 3350 MB uncompressed size (or larger) in archive . It does not happen with a file of 3300 MB uncompressed size (or smaller) in archive.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
Windows 10 Explorer's "Send to Zip" for big files (3500 MiB) creates Zip64 Extra block in local file header.
But if both uncompressed and compressed sizes are smaller than 4 GiB, it doesn't store 0xFFFFFFFF in 32-bit fields as expected by Zip64 specification.
So 7-Zip reports about that error.
Probably I can change 7-Zip code, so it will ignore such minor errors in zip archive, created by Windows 10.

Plese try to create some another small example of such archive and attach it here.
I can not create a small example of such archive, because the problem happens with large files (see attached screenshot).
Please try to find smallest size with error and write details:
How many files in archive, and what uncompressed/compressed sizes?
