Google 2 Factor Authentification app failing to start

[ligand7]

Hi,
my google 2 Factor authentificator doesn't work (gave me codes wich did not fit), so I tried to synchronize the app. This also did not work. Now it is impossible to open the app ("authenticator was stopped unexpectedly. Try again").
I do not have all my QR codes for regeneration.
Perhaps there's a simple solution, something about wrong settings. My cellular is quite old (samsung ace 2). Can someone please help, becouse I can't get into my crypto accounts?

Thanks a lot!

Looks like your google authenticator is corrupted try this method and hope can solve your issue..
Open settings>Look for application list or manager> Look for google authenticator app..  After that just clear cache don't click  delete or clear data just clear cache and try again.

Let me also know if your phone has antivirus installed if not maybe you are infected with sexy virus or monkey virus so beware.. try to download ESET its a free app for android phones..

If its still "unexpected try again" try to reboot phone and open your authenticator again.

Thanks a lot for your help!
Cache is empty so I can't do anything there. I got no antivirus program on the cellular (I think tomorrow I buy a new one anyway, because it is very old).
Any idea left?

After my Google Authenticator started to fail, I switched to Microsoft Authenticator. Have been using it for months, haven't noticed any bugs yet.
