Troubles on creating landscape in multi-user mode

Hello!
During session we encoutered the issue when one of us create a landscape.
Here is the log:

[2024.04.13-17.51.32:830][311]LogConcert: Display: Synced activity ‘2’ produced by endpoint ‘1F33AA7E4952ACEFFE9118BFCE280B9E’: Roman joined the session.

It should be mentioned that I have no D disk. Mate has it, but he reinstalled UE5 with this disk disabled but the error persisted.
Even if I’m hosing and I create landscape I got this crash message.
