A few days ago, it was not possible to upgrade automatically (to v4.2.6 beta X from v4.2.5 final and to v4.2.6 beta new from v4.2.6 beta old) due to this error. The good news is, I tested all of them and observed that this error was corrected🥰. It can be upgraded to the latest final and beta, including previous final and beta versions. Thank you so much.
