Russia continue its lunar exploration efforts despite loss of its Luna-25 moon lander

Russia will continue its lunar exploration efforts despite the recent loss of its Luna-25 moon lander, according to Russian leader Vladimir Putin.
Luna-25 launched on Aug. 11 and entered lunar orbit five days later. However, the spacecraft's engines suffered an anomaly during an intended orbit-lowering maneuver on Aug. 19, burning for 127 seconds instead of the scheduled 84. This resulted in the lander smashing into the lunar surface two days ahead of its scheduled high-latitude landing attempt.

What about Flyback Energia? What about something 100% reusable to match Starship / Booster?
