Thank you for letting me know the issue and the detailed report.

Coffeelake GPU does not support --ctu 64, so this was the cause of the error. There was a check for this ctu parameter, but the check was broken from QSVEnc 7.00 (which works fine at QSVEnc 6.10). QSVEnc 7.35 will check ctu support properly, and should be able to avoid this error.

Thanks for the fix, 7.35 works like a charm
