Don't you know that just recently another tranche was made to service Russia's external debt, and the payment from the blocked accounts was successfully completed. Although there was a real risk of a technical default, and Putin even gave instructions to service the external debt in rubles.

Russia has had a steady budget surplus for many years and its external debt is relatively low. I'll tell you more, now all imports to Russia are blocked by almost 100% and exports are blocked by only 30%. This makes Russia's foreign trade balance very strongly positive, although it was positive before. I hope you have enough economic literacy to understand that a positive foreign trade balance favorably affects the national currency.

Rumors of the death of the already twice "torn to shreds" (the first time after the annexation of Crimea in 2014) of the Russian economy are greatly exaggerated. Try to learn how to live with it somehow.
