Installing the editor without the game.

Basically, I've been working on a map for a long time, then I forgot about it, and the other day I decided to play it. After that, I found some flaws, and when I tried to fix them, I couldn't. As soon as I go into editing the primary parameters, secondary skills, or changing the number of creatures, the resolution of this window becomes a ridiculously small and incorrect size. I tried reinstalling. I downloaded other versions of the game. I searched the internet for some kind of patch for h3maped, but nothing changed. What should I do, please advise? This is Heroes 3.58. I've been playing it for about 20 years. It has always been possible to edit it without any problems.
