Heroes of Might and Magic V: Tribes of the East – saving doesn’t work. Auto-translated

Hello everyone. I'm having an issue with HOMAM V: Tribes of the East. Saving doesn't work; the game doesn't save, and the error message says there's not enough space on the disk, even though everything is fine. The profile and game settings aren't being saved either. There's a profile folder in the save folder, but it's empty. It was working fine not long ago, and the reason for this is unknown. I've reinstalled the game and Steam, but it didn't help. If it's relevant, there's another issue: the controls aren't working – camera rotation, zooming in, and zooming out. I'd be grateful for any help you can offer.

either it's a bug in the game/system, or there's a problem with the hardware. As for saving, this issue occurs when there's a faulty mod, a corrupted game executable, or simply when the system fails to save the game (e.g., insufficient storage space, policy restrictions, etc.).
