Maybe, but at the current stage of information you have to find it alone. You didn’t even mention your OS, not where you saved your files or anything useful. Suggestion: start praying or ask somebody who has access to your computer.
Some things to check:
- Storage on not connected cloud storage
- rights management / anti-virus
- icon cache corrupted
Without accessing your files:
- Can you start LibreOffice?
- If yes, try to open a file from the menu File>Open
Good luck…
PS: Changed tag from base to common. You didn’t mention anything related to our database module Base
