Error creating new user

[Loges]

Hi all,

An issue that I've only discovered on a site I've recently upgraded from 3.0.42 to 3.0.88.  This does NOT affect SuperUsers but DOES affect users who I've set up as Admins with user-admin permission.  If one of those users tries to create a new user it throws the following error.

 

Has anyone else seen this, can replicate etc?  I assume something has changed in the core as part of the User upgrades a few versions ago, but no idea why it would work for SuperUsers but not others.  

 

Error: Uncaught TypeError: Argument 2 passed to ProcessWire\ProcessUser::checkSaveRoles() must be an instance of ProcessWire\User, instance of ProcessWire\Page given, called in /sitepath_redacted/wire/modules/Process/ProcessUser/ProcessUser.module on line 356 and defined in /sitepath_redacted/wire/modules/Process/ProcessUser/ProcessUser.module:368
