The engine crashes when renaming a localizable asset inside an L10N folder. The engine attempts to associate it with the original localizable asset, but it is unable to find it and ends up accessing an invalid memory pointer.
This bug has also been tested with ue5-main branch.

1-Open an Unreal Engine project.
2- Import a texture or any localizable asset and name it MyAssetA.
3- Inside the Game folder, create an L10N folder. Then create a region folder inside it, for example: L10N/fr/.
4- Copy and paste the texture from the Content folder into the newly created L10N/fr/ folder.
5- Rename the texture inside the L10N folder to MyAssetB. After renaming it, rename it again back to the original name, MyAssetA.
6- The engine will crash in the FAssetRenameManager::RenameAssetsAndVariants method.
