Restoring Snapshots of VB 7.0.20 failing in 7.1

[iv3l.nuh]

I am running the latest Debian Bookworm 12.7 with 6.1.0-25-amd64 kernel. I had the 7.0.20 VBOX where I created simply an Ubuntu server VM and a Client VM. Updated the VBOX to 7.1.0. My V-machines created in 7.0.20 work fine, but when want to restore to previous Snapshots created under 7.0.20, in the 7.1.0, an error occurs:

The VM session was aborted. Result Code: NS_ERROR_FAILURE (0x80004005) Component: SessionMachine Interface: ISession {c0447716-ff5a-4795-b57a-ecd5fffa18a4}

Thanks for the report. A fix has been putback in revision r164816 of the development branch of VirtualBox and is available now in the development snapshot Testbuilds. Could you download a snapshot with a development revision build with revision >= r164816 for your host platform type and try it out? Thanks!
