[BUG] Not able to run app after some settings change

[Viipiin]

Getting above error when running XRMToolBox for few of the settings update

[MscrmTools]

This is because you are using beta version of connection controls. It seems it does not work as expected... Can you change this settings and only use stable version ? I will remove this beta version that seems to have an issue

Where or how can I change the settings please? XRMToolBox does not open after closing the error.

[MscrmTools]

By default, XrmToolBox.Settings.xml should be located in c:\users\your_profile\appData\Roaming\MscrmTools\XrmToolBox\Settings

But I don't see why it should block XrmToolBox from starting...

It could block you to connect to an environment but if you go to settings page, you should be able to disable use of pre release version of connection controls. Then it should download latest stable version

I'm having the same issue after updating to latest version and no longer able to open XrmToolBox

Also setting ConnectionControlsAllowPreReleaseUpdates is already set to false

[MscrmTools]

Please download latest version from website and overwrite your XrmToolBox folder content
