I've just pushed a fix for that regression. was an added security check that was incorrectly
triggered when reading band 23.

Hum, are you really sure about that.. ? if gdal_translate cannot work, I can't see how gdalwarp
could (if you use -overwrite to make sure creating a new file, and not updating something
I get now gdal_translate and gdalwarp to work, but due to how GRIB decompression works,
for performant operation, I strongly suggest to first gdal_translate to a band interleaved
GeoTIFF file, and then gdalwarp it:
gdal_translate blend.t16z.master.f001.co.grib2 tmp.tif \
-co tiled=yes -co compress=zstd -co interleave=band
gdalwarp tmp.tif out.tif -t_srs EPSG:4326 -overwrite -co tiled=yes
