Ark assets migration to UDK 4.25 project

I didn’t suceed to migrate assets from the Ark Editor sandbox to a 4.25 project. The project crashes while opening. The Ark editor doesn’t have sequencer only matinee.
Any helps are welcome

ARK game assets are not provided with license to use them in any projects other than ARK mods.
The ARK editor has also had significant deviations from standard UE4 even without considering the huge version gap between 4.5.1 and 4.25
You both shouldn’t and probably will not succeed in this effort.
