Cannot copy/transfer MP4 output file after successful rendering & play

I recently upgraded my Premiere Elements from 2015 to the new 2023 version. It all works great until I go to transfer the rendered file (MP4) to a USB stick. The output MP4 file is 10.3GB. It plays just fine, but when I go to transfer to a blank 64GB USB stick, it says there is not enough room on the stick. I formated the stick ahead of time so it is blank. 

I tried this on 2 computers and I have the same problem. I failed on my Windows 10 desktop. I then archived the project to a USB stick and put it on my new Windows 11 laptop. Same problem. The error said the destination device was not large enough for the file MP4 file being transferred.

I'm completely bewildred by this behavior. I believe it must be a Premiere Elements problem, not a Windows file system problem. I can transfer much larger files/folders of various types to and from the same computer and USB stick without a problem. 

Any suggestions? The only thing I can think of is that when I archived the project for transfer to my Windows 11 laptop, I choose the "copy project" option to archive the entire project including all media assets. Maybe I should have chosen the "Archive Project"? But that doesn't explain why the problem occurred on the originating Windows 10 desktop from which I did the archive. 

Thanks,
