Dnn.Platform: Error during upgrade from 9.0.2 to 9.2.2

Summary

I’m having problems upgrading an existing website from version 09.00.02 to 09.02.02. Would it be possible to point me in the right direction to solve this?

Extended description

I’m getting the error below, apparently while trying to update to 9.1.0, and the update hangs.

Error log (if necessary)
