In short, for Russia to lose would be the end of Russia. They have to be seen as hitting their objectives (they’ve hit a few so far). Ukraine is massively out gunned, but has more manpower active. That said, I don’t see an outcome where Ukraine can regain any territory and will likely only lose more. That will further embolden Russia and will keep them from surrendering at the very least.
