Hi mikdac,
Thanks for posting here in Apple Support Communities. As we understand it, Finder won't find your files when you search in specific folders. Lat's have you try starting up your Mac in safe mode to see if you're able to find the files in your folders. See: Start up your Mac in safe mode
"Start up your Mac with Apple silicon in safe mode
- On your Mac, choose Apple menu > Shut Down.
- Wait for your Mac to shut down completely. A Mac is completely shut down when the screen is black and any lights (including in the Touch Bar) are off.
- Press and hold the power button on your Mac until “Loading startup options” appears.
- Select a volume.
- Press and hold the Shift key, then click Continue in Safe Mode.
- The computer restarts automatically. When the login window appears, you should see “Safe Boot” in the menu bar.
Start up your Intel-based Mac in safe mode
- Turn on or restart your Mac, then immediately press and hold the Shift key until you see the login window.
- Log in to your Mac.
- You might be asked to log in again.
- On either the first or second login window, you should see “Safe Boot” in the menu bar.
Verify your Mac started up in safe mode
If you’re unsure whether your Mac started up in safe mode, you can use the System Information app to check the mode.
- On your Mac, press and hold the Option key, then choose Apple menu > System Information.
- In the System Information app, select Software in the sidebar.
- In the System Software Overview, look at the value listed next to the item labeled Boot Mode.
- Safe: The Mac is using safe mode.
- Normal: The Mac is not using safe mode."
Keep us posted on the results.
Have a great day.
