Hi @Frisch12. This bug is being tracked here: #1343

I'm happy to tell you that a fix is already in progress: #1450

You can easily apply that fix immediately in your Arduino IDE by a simple adjustment to the IDE's advanced settings. I'll provide instructions:

1. If you still have the problematic "esp32_marauder" sketch open in the Arduino IDE, select File > New from the IDE's menus and then close the window with the "esp32_marauder" sketch open.
2. Open the "Command Palette" via the Ctrl+Shift+P shortcut (Command+Shift+P for macOS users).
3. Select the "Preferences: Open Settings (UI)" command from the "Command Palette".
   This will open the "Preferences" tab in the IDE.
4. In the "Search Settings" field, type editor.maxTokenizationLineLength
5. Change the value of the "Editor: Max Tokenization Line Length" setting from the default 20000 to 500
6. Close the "Preferences" tab by clicking its X icon.

You should now be able to open the "esp32_marauder" sketch again without experiencing those performance problems.

It is best to have only a single issue per subject so we can consolidate all relevant discussion to one place, so I'll go ahead and close this in favor of the other.
