Exactly. Things have not gone very well in Russia in recent years. Average people getting poorer. Many casualties in Covid after population has been going down already for longer time. Russia's economy being pretty small internationally if you take the size of the country into account.
Putin just wants to move domestic attention away from all the misery that people will hold him reponsible for. Now war will dominate the agenda. And if someone complains about life getting worse, it's the war, not the incapable president.
