Problems Adding New Textures/Materials

Hello everyone, In the 2024 version, I am unable to add new textures (new standard material). As soon as I try to load individual channels (for example: roughness, normal map, height map, etc.), white or dark files are loaded instead. I tried both PNG and JPEG files. In both formats, the individual channels remain white or dark. Has anyone else encountered the same problem? I am working on a Mac, and I converted the working file from the TM 2023 version. Thanks for your help. Best regards, Nik

After a lot of trial and error, I finally found the mistake. I noticed that I can load textures that are not located in the texture folder I specifically created for the TM file. This means the problem lies somewhere in the link between the (texture) folder I already created for the 2023 work file. Until now, I had only tried loading textures/material channels from that folder. But then I randomly tried loading an image from my Downloads folder—and it worked.
