Our DNN site is version 9.1.1.  When we create a new login, if they enter the correct username and password, the following error is generated if they are an administrator.  When we make them a SuperUser, they are logged in as expected.  This only happens in Portal 0.  We have 25 portals in the installation, and they work fine.

It is not exactly the same as you are experiencing but https://github.com/dnnsof...Platform/issues/2413 is also addressing 'redirect after login' issue. The code that should be fixing it (https://github.com/dnnsof....Platform/pull/2275) was in relation to multi lingual and fixed in 9.4. If you were to upgrade, I'd bump to 9.4.1.
As you are on 9.1, please beware that a lot of code has been deprecated. It is still very doable in most cases but take the right steps.

Did you ever solve this problem or find a workaround?

Just had this with DNN 9.9.0 which seems to give an error when creating a new user (error message displayed) but then still creates the user.

Scenario: Imported a project. Added a new user, which displayed an error message but did actually create a user. Added Administrator role to user. Tried to login as user but Server 500 error and admin log displays error mentioned by Tom Wolfe. The site did have a redirect tabid set after login but think this is a red herring.

Workaround : Error was due to preferred timezone for user. Went to profile admin and set preferred timezone to list timeZone and then set a valid timezone for user. This allowed the user to login but even though they were administrator they didn't have edit permissions (pen) or missing half on the persona menu items. So added Registered user role in through the database in userrole table for that user and portal and then everything works fine.
