Hi @Taryn and welcome to our adorable Community 😊 I am sorry this is happening to you. It's quite odd that it happens just on that specific level. Are you playing on Facebook or king.com?
As it is only on this level, none of this helped. It freezes when I have 21 moves left. If I play another level, there is no freeze. When others play on this computer, there is no freeze. Only level 1850.
It doesn't happen on my phone app. Looks like I will have to win this level on my phone and then go back to my computer. LOL. That is one way to fix the issue.
