50750 * 62835 cells corresponds to a temporary file size of ~12 GB,
which requires large file support (LFS). I don't think that this works
on Windows at present, in which case you'll need to down-sample the
input file first.

(Raster maps are normally compressed, so the actual input file could
be under the 2GiB limit, but the temporary file required by r.proj
isn't compressed, as it needs random access).
