Problem 44761. Lights Out 9 - 5x5, light-only solution? II
Lights Out is a logic game wherein all lights need to be turned off to complete each board. See the first problem in the series for an introduction.
This problem contains boards that each require any number of moves to solve. The function you write has to determine if the initial state contains a potential answer—i.e., if toggling any given subset of the starting lights is sufficient to solve the board.
Prev.: 5x5, light-only solution? I — Next: 5x5, with wrapping, 6 moves

Test problem 21 is faulty.
It has been updated.
Test suite has crashed again plz fix
@ Nikolaos: are you sure it's the test suite and not a server error? If you get the following message, it is due to a temporary server problem, not a specific problem: "While evaluating the solution, the server encountered an error caused by temporary unavailability of MATLAB Service. Wait a few minutes for the MATLAB Service to return, and then rescore." If you are getting this error, simply try the problem again later or on a different day.
