I have uploaded a demonstration video of the issue. My C4D version is 2026.2

Hi @123456_1
Can you please check what you have in this directory %appdata%\Roaming\Maxon\Maxon Cinema 4D 2026_\tex\asset_browser\
We make temporary copies there for textures from the asset browser. Is it possible that there’s either an empty file called Legacy or Legacy\HDRIs instead of directories? If yes deleted them and try again.
For example here I accidentally selected the HDRIs category which ended up copying a 0 byte file, preventing me from using any textures from within that HDRIs directory. I will check if we can handle that in a better way.
If that’s not the case please check your console for errors.
@bozhidar_ivanov Yes, it returned to normal after I deleted the file. However, whenever I close C4D and then reopen it, the same issue still occurs when I try to add a texture again
