Problem with HDR panaroma with 4.6 on Android / Meta Quest?

Godot Version

Godot 4.6 stable

Question

I used a hdr as panorama sky material with 4.4.x and it works fine on Android, e.g. in Meta Quest. With the new Godot 4.6 stable version only an error appears and the world environment is not loaded again. I reimportet the file with different settings, e.g. VRAM Compressed / High quality but it seems the android loader still use the BPTC compression, instead of the ASCT one, which is needed on Android. I hope someone can help me.

Thanks in advance!
