This is the problem, right?

I had this problem with Hong Kong and Cook Islands. It only happened when I imported the team with the players and to the default slot of the team. I don't know what can be causing it, but I found a workaround (that will take some time):
1 - Import the team normally (to the correct slot) but don't tick the box to import player data (so the team imports without players), so you'll have the right kits, flag, etc.
2 - Import the team again but to another unused slot, like a classic team for example, but this time you apply the player data.
3 - Change all the players from the slot you applied the player data to the correct slot of the team. Then make the formation/tactics correct and you're good to go (if you want, do what I did, take a picture of the original formation with your phone or something before you transfer the players so you can recreate it on the right slot)
I did this for both teams and I was able to save and play. Then, I exported the teams after this workaround just in case something happens I can import it again without crashes. Very odd bug, I hope it doesn't happens to me again.
