Frequent export errors ("not enough memory") in LR Classic v11 (Win 10)

[beta!sheet]

Since updating to LR Classic v11.0.1, I'm seeing export failures on almost every multi-file export attempt. I've never had this issue before on this machine. The system has 32GB of RAM, of which maybe 80% is used in total by all apps, but LRC only uses approx 9-10GB, even during export. I don't see how memory would be an issue.

Are there any error logs or similar that would help investigate what is going wrong here?

Where are you exporting to? How much hard drive space?

What happens if you close other apps before you do the export?

What happens if you restart the computer, open only LrC, and do the export?
