It seems you have a problem with your installation of the PROJ library. Most likely, you have multiple versions of PROJ installed and GDAL is not using the right one. Maybe you can fix it by setting the PROJ_LIB environment variable to the path to the right proj.db file (see https://gdal.org/drivers/raster/gtiff.html#georeferencing).
