Hi there! I see you're running into a "Range Error: Maximum call stack size exceeded" problem with the Jigsaw Puzzle Plus app on your Windows device. That error usually happens when a function in the app calls itself so many times that it runs out of space on the call stack — basically, the app gets stuck in a loop or too many nested calls, which it can't handle.

To help you best, could you tell me when exactly this error pops up? For example, does it happen when you start the app, during gameplay, or when you try to load or save puzzles? Also, do you notice if it started after a recent update or change?

Meanwhile, here are some simple steps to try that usually fix this kind of issue:

1. Restart the app and your PC: Sometimes a fresh start clears up memory issues causing such errors.

2. Clear browser cache: Since your device uses WebKit (a browser engine) on Windows, clearing the browser cache can remove any corrupted stored scripts causing this.

3. Update your browser and Windows: Having the latest updates ensures bugs are fixed and the app runs smoothly.

4. Disable browser extensions: Some add-ons can interfere with app scripts and indirectly cause errors.

If you've done any of these, please let me know. If not, we can walk through them together or dig into more advanced steps like checking for corrupted puzzle files or settings within the app.

Does any of this resonate with what you’re experiencing?
