Hi there! I understand that your Stormshot app is getting stuck at 20% during the boot process right after an update. Let’s work through this together.

To get a clearer picture:
1. Did the app freeze while loading the update itself, or after the update was applied when you launch the app?
2. Are you using the app on your PC (Windows 10) through WebKit, or is it a different device?
3. Have you tried restarting your device or closing and reopening the app already?
4. Have you tried reinstalling the app since the problem started?

While I wait for your answer, here's the straightforward approach we can start with:

### Step 1: Restart Your Device and Network
- Sometimes, a simple reboot can clear temporary glitches that block app loading.

### Step 2: Clear Stormshot Cache and Local Data (if accessible)
- In Windows, if you run Stormshot via a browser or app: clearing cache can resolve loading hangs.

### Step 3: Reinstall the App
- Uninstall Stormshot completely from your system. Then, download and install the latest version fresh. This helps because sometimes updates don’t complete properly or corrupt files. Note: This may affect any saved progress if not backed up.

### Step 4: Check for System Updates
- Ensure Windows 10 itself is updated fully. Outdated OS files can sometimes cause compatibility issues.

If these don’t work, there might be a known issue with the recent update. Some users have reported similar loading hangs specifically around percentages like 20% after the latest update, and reinstalling solved it for many2.

Let me know if you've tried any of the above or if you want me to guide you through any step!
