All of my files and collection are deleted!

Good morning,
During lockdown i entered a lot of cards into some very old files (not synchronised), and it was working very well.
I haven’t used Anki for about a month but had no major change on my computer, yet when i tried to see my collection, all of my collection was gone!
Anki is suggesting me to “check database” but when i try to do it, it gets back on the same alert message:
"*To make sure the problem is not related to your package, please use the menu Tools > Check Database. *
If this does not solve the problem, please copy the following in a bug report :
Traceback (most recent call last):

  • File “aqt/webview.pyc”, line 152, in _linkHandler*
  • File “aqt/toolbar.pyc”, line 74, in _linkHandler*
  • File “aqt/toolbar.pyc”, line 97, in _syncLinkHandler*
  • File “aqt/main.pyc”, line 589, in onSync*

  • File “anki/db.pyc”, line 43, in execute*
    pysqlite2.dbapi2.OperationalError: attempt to write a readonly database"

My account wasn’t synchronized because it wasn’t working …
Do you have a solution please ? I don’t know where to find the “bug report” and I would like to get it all back asap :sob:

Thank you in advance! Have a good day
