Can't sync files larger than 1GB

I use Bvckup 2 Pro to sync a local work folder to a folder on Google Drive File Stream. It generally works well and hasn't caused me any problems. Lately though, I've had occasion to create a few large files (over 1GB each). For some reason, these files simply will not sync when using Bvckup. If I manually copy them to Google Drive File Stream in the Windows 10 File Explorer, they upload/sync just fine, but they always fail in Bvckup.

Has anyone else experienced this? Is this a known issue? The errors I get always end with "failed with 1450". Mostly, the errors are WriteFileAsync(), but occasionally I'll get a SetEndOfFile error, as well.

Any help on this would be greatly appreciated.

As per [1] error 1450 stands for "Insufficient system resources exist to complete the requested service."

Hard to say which "resource" this is in reference to exactly, but what you can try is to throttle down program's copying module to use just a single IO buffer. See here for how to do this -

If this doesn't help, you can always force bvckup2 to use Windows native file copying routine, which is the same thing that Windows Explorer uses. I can explain how to do that if needed.
