Looks like Luna-25 Failed
On August 19, in accordance with the flight program of the Luna-25 spacecraft, it was planned to issue an impulse to form its pre-landing elliptical orbit.
At about 14:57 Moscow time, communication with the Luna-25 spacecraft was interrupted.
The measures taken on August 19 and 20 to search for the device and get into contact with it did not produce any results.
According to the results of the preliminary analysis, due to the deviation of the actual parameters of the impulse from the calculated ones, the device switched to an off-design orbit and ceased to exist as a result of a collision with the lunar surface.
A specially formed interdepartmental commission will deal with the issues of clarifying the reasons for the loss of the Moon.
