I don't know this camera. Apologies if I state the obvious here...
Are you sure you have the right uptake spool? Do you mean the spool itself turns on its shaft?
For what it's worth, the manual (with Russian text) is at

It looks like they want you to insert the film backwards through the slot in the spool, but otherwise there doesn't seem to be much that's tricky. Does your uptake spool look like theirs?
The rewind release seems to be a button on the base; does that press something on the uptake spool itself? It may be something in the rewind mechanism is stuck.
