425 Error while transfering data: TLS session of data connection not resumed

Hello,
new FileZilla server in options no longer allows to disable Require TLS session resumption on data connection on the server side from security reason.
now when I use WinSCP to connect with FTP server with explicit encryption after I want create file/folder I have error:
425 Error while transfering data: TLS session of data connection not resumed.
I tested other FTP software and this error only exists in WinSCP.
I report this bug on FileZilla server forum: https://forum.filezilla-project.org/viewtopic.php?t=54027 but they sent me back to WinSCP because the error only occurs in this program in other software I tested I don't have this error when I connect to FTP with explicit encryption.

Thanks for your report.

This issue is being tracked already:
Bug 2018 – TLS session resumption is not working for subsequent FTP transfers with TLS 1.3 when the server requires reuse of the session of the previous transfer

Can you send me an email, so I can send you back a development version of WinSCP for testing? Please include a link back to this topic in your email. Also note in this topic that you have sent the email. Thanks.

You will find my address (if you log in) in my forum profile.

May I email you for access to a development version as well? Or can we please get a release candidate or such posted, or even an ETA for a release?
