Departure without error (Kingdom Come: Deliverance)

Played 21 hours in the game. The game started crashing to desktop without any error. On one save it crashes stably after 4-5 minutes, on the other after a minute. Before that, I noticed that the save began to load longer than before. The main plot was passed quite a bit, the quest with the investigation of the massacre in Neuhof was completed, I did not go to Uzhitz, I was engaged in additional. quests and skill upgrades.
Pirate game, version 1.8.1 (that is, not the current version), I use the save mod without schnapps. A year ago, when playing on the same repack, there were no problems on the same system.
I tried to reinstall the game, load a slightly earlier save (1 hour difference between them), without using the mod - nothing helped.
Unfortunately, at the moment there is no way to download the current version of the game, which, perhaps, would save the situation. Therefore, I hope that someone can tell a way out of the situation, if there is one of course.
