Multiple errors appear in the Console window when reimporting a .scenetemplate asset that contains a texture with width/height not divisible by 4

This stems from the fact that support for DXT/BC textures with dimensions that are not divisible by 4 was dropped in 2021.2 (see https://unity.com/releases/editor/whats-new/2021.2.0 "Graphics: Restricted DXT/BCn texture compression to textures with multiple-of-four width and height. This ensures the same behavior as the Texture Importer and requires multiple-of-four dimensions when compressing.") However, it is indeed possible to still have serialized Texture data where these non-divisible-by-4 dimensions are used (for instance, after upgrading to a newer Unity version). The issue has been fixed by decompressing the erroneous Texture. Note that this behaves similarly to before the restriction; even then, the Texture was uploaded to GPU in uncompressed form. The only difference is that, now, the Texture is also kept in memory in uncompressed form (whereas before, it was only decompressed before uploading). A warning will indicate that this happened; ideally the erroneous Textures get fixed (by rescaling/padding if applicable, or storing them in a supported format)

2022.1 has reached end of life so the issue will be fixed in a newer version.
