Hello sf4915,

Welcome to the QuickBooks Community! I will be happy to assist you here. First, let's do some basic troubleshooting steps for your memorized reports. To begin, re-sort your Memorized Reports list. Kindly follow the steps provided below:

1. Go to the Reports menu.
2. Choose Memorized Reports, then select Memorized Reports List.
3. A pop-up window will appear. Click on the dropdown icon beside  Memorized Reports, then pick Re-sort List.
4. Select OK when you get the prompt "Are you sure you want to return this list to its original order?".

After that, run the Rebuild Utility that supports the repair of the data damages in your company file.

Here's how:

1. Go to File, then select Utilities.
2. Select Rebuild Data.
3. Choose OK if you receive a warning message that states to back up your company file.
4. Click OK when you get the notification Rebuild has completed.
5. Run Verify Data to scan for remaining data impairment.

From there on, try accessing your memorized report, and if you still cannot gain access to it,  please let me know! 

I will be looking forward to your response! See you later.
