Hi there! I understand that the RV Trader app on your Mac is showing an 'ops' error and won’t open. Let’s get this sorted out.

First, could you please clarify a couple of things for me?
- Are you using the RV Trader app downloaded on your Mac, or are you accessing it through a web browser?
- When exactly does the 'ops' error appear—is it immediately on launch or at some other point?
- Have you tried any steps already, like restarting the app or your Mac?

Once I have that, I can provide you with the most suitable steps. Generally though, here’s a straightforward approach to try first on macOS Catalina (10.15.7):

1. Restart your Mac
Sometimes a simple restart clears up temporary glitches.

2. Force quit and relaunch the app
- Click the Apple menu > Force Quit
- Find the RV Trader app in the list, select it, and click Force Quit
- Then try opening the app again.

3. Check for App updates
- Open the App Store, go to Updates, and see if there's an update for RV Trader. Updating might fix bugs triggering the error.

4. Clear cached data for the app
Since you’re on macOS, cached files are stored in your Library folder. To clear these:
- In Finder, press Shift + Command + G
- Type ~/Library/Caches and press Enter
- Look for any folders or files related to RV Trader and move them to Trash
- Restart the app.

5. If it’s a web app issue
- Clear your browser cache and cookies.
- Try a different browser (Safari, Chrome, Firefox) to see if the problem persists.

If none of these help, the 'ops' error may relate to a temporary server issue or data corruption on the account side. In that case, I’d recommend contacting RV Trader support directly at [email protected] for more backend assistance, but let’s see if these steps solve it first.

Please give these steps a try and let me know how it goes! Are you satisfied with this plan?
