Samurai Persistence

Hello. There aren't that many maps with the Naga, and even fewer Campaigns, so I'm very disappointed, BUT the Campaign is unplayable... you can complete the first 4 days, and then, after capturing Yolsir, the game completely freezes, no button works, and you can't open the console. To avoid banal advice, I'll say right away - I have Heroes 3.1, I deleted the game, reinstalled it, and immediately installed this Campaign, so there are no third-party mods or scenarios. The profile is new, the game is launched from the H5_Game.NCF shortcut in the bin folder. The conflict related to music files, as Delvi suggested, is also ruled out. I checked by not putting the music folder in, with it and without it - it freezes. I assume that Mr. Grigory, with his latest bug fixes, somehow affected something. Because, apparently, there was no such error before.
