Matomo Plugin not showing reports

After the recent update, matomo has stopped working, it shows a blank page when I go to reports, no reports are shown there except the matomo button and UI.

When I go to diagonistics -> System reports, I see the following things:
1) Max Packet Size warning It is recommended to configure a ‘max_allowed_packet’ size in your MySQL database of at least 64MB. Configured is currently 16MB.

2) Proxy header HTTP_X_REAL_IP A proxy header is set which means you maybe need to configure a proxy header in the Advanced settings to make location reporting work. If the location in your reports is detected correctly, you can ignore this warning.

3) Proxy header HTTP_X_FORWARDED_FOR A proxy header is set which means you maybe need to configure a proxy header in the Advanced settings to make location reporting work. If the location in your reports is detected correctly, you can ignore this warning.

I tried troubleshooting and when I click on Archive reports this is the error I receive:
