Hello,

Do you have enough free space on your "C:" drive?

Try installing/reinstalling the latest version of the .NET Framework:

Do you have this issue with other profiles/fightclasses?

I’m running bots on 3 PCs, and each of them has enough RAM and space on the C drive. It doesn’t depend on that. I thought the same, so I expanded the disk space, upgraded the RAM, and added a new SSD — no difference. I also reinstalled .NET, but that didn’t help either.

The strange thing is that everything works fine when running 1-10 bots, but when the total reaches 30-40 simultaneously, after a long period of operation, .dll errors start appearing.

Do you use Relogger? If yes, try to restart bot/game more frequently (like every 6h). Or use one WRobot folder per game, but that requires much more work for maintenance.

Yes, I'm using Relogger for this. As I understand it, I have to use 1 Wrobot folder for 1 Wow client, right? 

If you use the "Relogger" you can try to schedule a bot restart every X hours. You can try on a bot to separate its folder (1 wrobot folder for 1 wow) to see if it solves the problem.
