Heroes of Might and Magic V: Tribes of the East crashes with the TE patch!

Good afternoon!
The problem is that I installed Heroes version 3.1, and then applied the TE version 6.7 patch.
I decided to test its functionality with scenarios involving bots. The vanilla game works fine, but after applying the TE patch, the game crashes as soon as the second day ends.
This doesn't depend on how you spend the first two turns, whether you engage in battles, or what map you're on. Even if you simply skip 2 turns, the game will freeze and eventually close with an error.
Please advise on a working solution to this problem.:smile33:

P.S. Compatibility mode doesn't help.
