Didn't the Apollo flight computer crash/have to be restarted during the landing phase?

No it didn't. It worked perfectly as designed. Buzz Aldrin left the rendezvous radar on, which together with the data from the landing radar overloaded the computer, but it handled it properly and kept on running. Great work, job well done.
"The Apollo flight computer was the first to use integrated circuits (ICs). The Block I version used 4,100 ICs, each containing a single 3-input nor logic gate. The later Block II version used dual 3-input nor gates in a flat-pack, approximately 5,600 gates in all. "
