Force Root Lock helped for me. If you have many assets in your blend space, select them all, and use this python script:


import unreal

# Get the selected assets in the Content Browser
selected_assets = unreal.EditorUtilityLibrary.get_selected_assets()

# Iterate over each selected asset
for asset in selected_assets:
    # Check if the asset is an Animation Sequence
    if isinstance(asset, unreal.AnimSequence):
        # Set the "Force Root Lock" property to true
        asset.set_editor_property("force_root_lock", True)

print("Force Root Lock set to true for selected Animation Sequence assets.")

This will enable Force Root Lock on all the selected animation assets.
