Russia has a fleet of ~200 Superjet planes which are handling a significant fraction of domestic traffic, but it's indeed not clear whether any more may be built after the 2022 sanctions. They also currently do not have engine replacements.

They demonstrated localized version of SSJ-100 with PD-8 engine in 2023. I'm not sure if it actually flew, but there were at least ground tests of the fully assembled aircraft.
Even if it's possible to retrofit existing fleet with PD-8, I can't imagine this happening at the rate at which the old (partly French-made) engines will be going out of order. So even that fleet will dwindle in numbers in the next years. Perhaps to zero, perhaps not - we'll see.
