import U# 0.x version (1.3.4) of https://booth.pm/ja/items/2683599 (see also #104)
Expected behavior:
I think U# should not migrate prefabs in such a case and show dialog to tell users instead.
Additional Information:
Provide any additional information here.
Some errors like this screenshot will be displayed because of U# migration. (This is error dialog on macOS but this error will also be happened on windows.)
