I can confirm this on commit 318c693.

It appears this is due to Windows-created ZIPs requiring a newer version to be extracted. This is likely a bug in the ZIP library we're using.

test.zip:                                                            Zip archive data, at least v2.0 to extract
godot-modifiers-plugin-4e88b9812c26d35673d6c12198aeb2f8cb2d9425.zip: Zip archive data, at least v1.0 to extract

# Extract `test.zip`, create another one using `zip -r9 test-v1.zip test`
test-v1.zip:                                                         Zip archive data, at least v1.0 to extract

$ zip --version

test-v1.zip can be loaded successfully:

Still valid in 3.2.4 beta3

[patrickdown]

Still an issue in 3.5.1

This likely affects projects using ZIPReader now that #65281 was merged in 4.0.beta.

I saw this while browsing github issues.

https://github.com/zlib-ng/minizip-ng Might be a better maintained fork of the minizip.

Might be worth checking if it supports the bug issue.
