It's pretty simple. Russia has a very resource extraction based economy. ~70% of its exports are petrochemicals and almost all of the remaining 30% are other raw resources, or low value added second tier resources like seed oils or steel. Prices of commodities are dependent on global demand.
Russia's economy has been kept afloat using various central bank tricks such as skyhigh interest rates. For example when the ruble was crashing due to Russia being decoupled from global trade, resulting in less goods, but the same demand for goods they jacked interest up to like 20%. People seeing this spend less money and save more money, so less money is actively in the market chasing that smaller supply of goods which tamps down inflation. But of course someday this money will come back into the system, similar to how the lockdowns harshly cut consumption and when they ended there was excess capital chasing fewer goods, creating inflation.

This is true but global conditions are going to get significantly worse for Russia if the USA's tariff rollercoaster puts it into recession, which seems very likely at this point. US recessions usually become global recessions and global recessions crater the price of energy. Russian budgetary assumptions are already based on a higher oil price than what currently exists.
Russia is a large country with a lot of resources but the late/post-soviet deindustrialization was never really undone so it remains highly dependent on imports from the globe for most high value added goods. They either need to get them from China or sanctions bust western imports via Kazakhstan or Azerbaijan.
