At this stage, none of these fixes seems to be an absolute slam dunk. But they are all worth trying, as other players have found that their issues appear to have been resolved. Alternatively, given that Activision is aware of the issue, you can wait for the next patch to arrive and hopefully fix it once and for all.

Why does Warzone keep crashing?

Since Warzone Season 3: Reloaded was released in May, Memory Error 1766 seems to have become much more common than it was previously.

It is, unfortunately, a fairly common pattern with COD games; an update or new content is released, and it leads to a torrent of glitches and errors, that take time to be ironed out.

On this occasion, Activision has at least listed it as a "known issue" that is under investigation or has a fix scheduled. But they say little else, to shed light on the situation.

Error 1766 (or 0-1766, to give it its full name) is a pretty major issue. It causes the game to crash, kicks players out of their games, and on some occasions, will cause a player's Xbox to shut down.
