[ZendTo] File Upload Error After upgrading to PHP 8.x

[Karl Bundy]

I have a RockyLinux 8 based Zend server that I am getting upload error messages after upgrading to PHP 8.x versions.  Things work fine with PHP 7.2 and 7.4, but when I upgrade to 8.0, 8.1, or 8.2 they all give the error in the Javascript console "ZendTo file chunk upload failed: Retry: Failed because Unknown upload error".  No file system permissions are changing between upgrades to 8.x, and the upload section of php.ini remains the same between 7.x and 8.x.  I have done google searches for upload issues with PHP 8.x and I don't see anything that is at all helpful.  Any guidance that the community can provide would be greatly appreciated!

Thanks!
