Hey there! Sorry to hear you're stuck with this crash after upgrading Ubuntu—let's try to work through this step by step, since you mentioned you're a bit of a noob, I'll keep things as clear as possible.

Here are some troubleshooting steps you can try:

• Update Lutris and test different Wine versions
  Ubuntu upgrades can sometimes leave your Wine or Lutris versions outdated, which might break compatibility with older games like Heroes3. First, update Lutris via terminal with:
  sudo apt update && sudo apt upgrade lutris
  Then, open Lutris, right-click your Heroes3 entry, select Configure, go to the Runner options tab, and try switching to an older stable Wine version (like 5.0 or 6.0—many classic games work better with these than the latest bleeding-edge releases).

• Recreate the Wine prefix
  The Wine prefix (the isolated environment where your game runs) might have gotten corrupted during the Ubuntu upgrade. To fix this:

  1. Right-click your Heroes3 game in Lutris and select Configure
  2. Go to the Wine prefix tab
  3. Click Delete to remove the old prefix
  4. Rerun the game installation wizard—Lutris will create a fresh, clean prefix for the game.

• Verify game file integrity
  If you reused game files from your Ubuntu 18.04 setup, they might have been damaged during the system upgrade. Try reinstalling the game from scratch: either use your original installation media/backup, or if Lutris has an official Heroes3 install script, use that to ensure all files are intact.

• Install missing 32-bit dependencies
  Ubuntu 22.04 might be missing some 32-bit libraries that older Windows games require. Run this command in terminal to install common necessary libraries:
  sudo apt install lib32gcc-s1 lib32stdc++6 lib32z1 wine32

• Check detailed Lutris logs
  The exit code alone doesn't tell the whole story. After the game crashes, go back to Lutris, click the Logs button next to your Heroes3 entry. Look for specific error messages (like missing DLL files, permission issues, or graphics driver errors)—these can point you to the exact problem.

Hope one of these steps gets Heroes3 running for you! If you need help with any specific step, feel free to ask for more details.
