Dedicated Server deletes grid on start since Oct '23 update

Since the last update in Oct '23 my Dedicated Server fails to load my base grid on start with the error shown below. When I run the Server a second time, the world loads, but the grid is deleted. I tried multiple save games and also turning off Trash Removal and PCU limits does not make a difference. When I import the backup save to a single player game, everything works and the base grid is still present.

App Version: 01_203_505

Environment.OSVersion: Microsoft Windows 11 Pro (x64)
