How fix importing assets and fbx bug?

Hello, I am sending this message to report an error or bug that I have been experiencing within uefn. I am uncertain if it may be related to the error of not being able to post new versions of one of my maps. Well, I am sending a video below that demonstrates the bug, where I am trying to add an image, which in this case is a texture inside a folder located in “content.” I have always done it this way since I started creating maps, and now this bug is happening. The image I tried to import cannot be the problem because it has already been used in other maps. Furthermore, I am also unable to import fbx (when I import them directly from uefn using the “import” option, which is the only one that works, the fbx comes out completely white and its materials also turn white). I have tried restarting uefn and even uninstalling and reinstalling it, but it does not work.
