Hi there! I see you're encountering a black screen followed by an "oops something went wrong" message when opening the Fresha app, and going to home shows the same issue. That definitely sounds like a problem we should get sorted out for you.

To make sure I guide you properly, could you tell me:
- Are you using the Fresha app on your Windows device's browser (WebKit), or is it a standalone app?
- Have you recently updated the app or your device's system before this started happening?
- Have you tried things like restarting the device or reinstalling the app yet?

This info will help me tailor the troubleshooting steps for you. Meanwhile, I'll suggest some initial fixes that often help with similar app display errors:

1. Force Close and Restart: Completely close the app or browser tab, then open again.
2. Clear Cache and Cookies (for Browser): Sometimes cached data causes loading issues. Clear the cache from your WebKit browser settings.
3. Check for Updates: Ensure both Windows and the Fresha app/browser are up to date.
4. Try a Different Browser (if applicable): Use Chrome, Firefox, or Edge briefly to see if the problem persists.
5. Restart Your PC: This refreshes system resources that might be stuck.

If these don’t fix it, the black screen can sometimes be related to graphics driver issues or app compatibility in Windows 10. You could try rolling back or updating your display drivers via Device Manager.

Let me know what you've tried so far or if you want me to walk you through any of these steps!
