Game crashes when aliens attack an undefended base

[KingGu]

When aliens attacked one of my bases, it happened that my soldiers needed some time to arrive.

So when I clicked the "Equip Defenders" button, I had no soldiers to arm, so I clicked on the world map and the game entered ground combat loading. When the progress bar was full, the game crashed.

Because an alien attack is bound to occur, but it takes time for the soldiers to arrive, there is no solution to the situation.

Fortunately, I saved the game not long ago, allowing me enough time to transfer soldiers to the base. But this incident occurred after a ground battle, causing all my progress losses.
