Yes! It's interesting, but I haven't found much about it. But in terms of timing, I have a theory.
During the war, Stalin allowed the Jewish Anti-Fascist Committee to be set up officially. These helped support the propganada war effort in the west, with a focus on Nazi atrocities including publicising what the Red Army found in the concentration camps and death camps.
After the war, Stalin found that the focus on the Holocaust of Jews was politically not beneficial to him - he wanted to highlight the millions of Russian/Slavic/Soviets killed, as an equal atrocity. His earlier experiment with Jews was to treat them as a nationality (like Ukrainians or Georgians), which means set up a semi-autonomous republic, for which he gave land in the Far East, near China. There were some tens of thousands of Jews moving there, but many did not leave their homes.
So I wonder if he felt Zionism was the "solution" to his Jewish "question". Stalin was, in contrast to most other Bolsheviks, not committed to third-world anti-colonial movements*, and this only increased after WW2, when his entire stance was about defending what he had conquered, rather than the ideological spread of communism. He didn't lift a finger to help Mao in the Chinese Civil War after it restarted in 1945. The Arabs inhabiting Palestine weren't even Communist, and the armies that later backed them were regressive royals. So this aspect, I don't think bothered him one bit.
The reason the timing matters is 1948, when he voted for Israel at the UN, and then shipped them arms, is also when he disbanded the Jewish Anti-Fascist Committee officially, and he would soon start an anti-semitic purge, known as the doctors' plot (where he killed most of those involved in the Committee), which ended only with his death.
*I know this because he made every third-world communist party tie itself in knots trying to follow the Soviet line on Nazism - first, it is a mutation of social democracy, then, we need to form a broad progressive front with social democrats to defeat it, then, it is not the main threat, unlike the west, finally, it is an existential threat to communism and working people worldwide. Trying to follow and explain this nonsense fatally discredited most foreign Communist parties. The Indian one backed British rule after Barbarossa, while Gandhi and lakhs of others were in jail.
