Hi there! I'm here to help you with the issue of not being able to upload files in DeNet Storage & Watcher Node. Let’s troubleshoot this together.

Could you please provide a bit more information about how the app is crashing? For instance:
- What happens exactly when you try to upload a file? Do you see any error messages?
- Are there specific file types or sizes that seem to cause problems?
- Have you tried uploading from different browsers, or is it only through WebKit on Windows 10?

With this information, I'll be able to guide you more effectively!

I want to upload files but it crashes after a while

Thank you for providing more context! Since the application crashes after a while while uploading files, let's go through some potential solutions.

### Step 1: Check File Size
Sometimes, larger files can cause the upload process to fail. Could you let me know the size of the files you are trying to upload?

### Step 2: Clear Cache and Cookies
If the upload process is being affected by accumulated data in your browser, clearing the cache and cookies often helps:
1. Open your WebKit browser.
2. Go to the browser settings.
3. Find the option for clearing browsing data or cache and cookies.
4. Select them and clear the data.
5. Restart your browser and try the upload again.

### Step 3: Check Your Internet Connection
A weak or unstable internet connection can also lead to upload failures. Ensure your connection is stable. You can conduct a speed test to make sure your internet is performing well.

### Step 4: Try a Different Browser
Although you're using WebKit, sometimes switching to another browser (like Chrome, Firefox, or Edge) can help resolve the issue.

### Step 5: Review Error Logs (if accessible)
If you have access to any logs or error messages post-crash, those can provide valuable insights into what is going wrong.

If none of these steps work, we might need to do some advanced troubleshooting. Let me know how it goes, or if you need assistance with specific steps! Are you satisfied with the solutions I’ve suggested so far?
