My Ash is locked and cannot be unlocked

Today, as usual, I launched Apex Legends to play. In the character selection screen, I noticed that my Ash was locked and couldn’t be selected. After the match ended, I returned to the lobby and checked in the Legend Locker, only to find that Ash was shown as locked again. When I tried to unlock the legend, it shows unlock with nothing. Please see the screenshots below — the last image shows the Trackers, which prove that I’ve played Ash many times before and had already unlocked her long ago.
