I don' know what to do! "Cannot initialize session/engine: Invalid or corrupt session state"

Hello! After crash I can’t to load session. Help me please!

Session “/home/kir/ARDOUR PROJECTS/staryi dom (snapshot staryi dom)” did not load successfully:
Cannot initialize session/engine: Invalid or corrupt session state.

—ERROR: Could not set session state from XML
ERROR: Session: failed to load active playlists
ERROR: Session: cannot create Playlist from XML description.
ERROR: Playlist: cannot create region from XML
ERROR: Session: XMLNode describing a MidiRegion references an unknown source id =4516
ERROR: Session: cannot create Region from XML description. Can not load state for region 'Take5_ZynAddSubFX 6-5.1'

And after the program crash all midi files in interchange directory have 0 or 26 bites size. I’ve lost all midi sources.
Thank you!

That is very odd. Which version of Ardour do you use, and on which OS?

Can you upload the .ardour session file, or if the session is small enough zip up the session-folder? And we can see if something can be salvaged.

Linux Manjaro 6.6.54-2 kernel, Ardour 8.6
Can you download from yandex? There are .ardour file and zip session (156 mb):
