Out of memory error when accessing a directory in a S3 bucket

WinSCP Version 5.17.10 Build 11087
Interface style: Commander
Windows Version 20H2 OS Build 19042.804

Using S3 protocol, when accessing a directory in a S3 bucket which contains 172 folders and 5633 files, after a while an out of memory error appears. Accessing the same bucket via SFTP is working without any issue.

It's not always the same error, see also these three reports:

The following error couldn't be reported using the Report button in the error message.

The issue is related to the display, see attached screenshot. When hovering with the mouse over it, the display is updated. Let me know if you need a session log.

Thanks for your report.
I have sent you an email with a debug version of WinSCP to the address you have used to register on this forum.

When I connect to the S3 location, after the connection has established, attached error messages appear.

It should not work. But it produces a trace log file. And I need you to send the log to me. Please read the instructions in the email I have sent you.

Sorry for the delay. I've been on holidays. Attached the trace log.

Thanks. I have sent your new a build. Please respond to the email, not on the forum.

Sorry, but can you please send it again? Someone has deleted your message. Many thanks!

I'm resending the email.
