Data loss after update

Everything was fine and now in the update all my spreadsheets have disappeared or lost their data I don't know what happened I had to go back to the previous version.

I see that I did not lose the data they are in the backup if a previous version is installed. When updating, data from several tables disappear.

Same issue with me. If I create a new spreadsheet, then the content is visible. All my old files are empty. Also, the changelog says that now the files can be seen using browser. In my case it shows that I don't have any files.
