Hi, Jaime,

I am glad that the project is working now as expected.

Please have in mind that for the latest internal builds we only provide dlls and Nuget packages, not an installation file.

Fixed by downloading Telerik_UI_For_WinForms_2022_2_711_Nuget_Dev and adding as nuget source the local folder where I saved the file.

https://docs.telerik.com/devtools/winforms/visual-studio-integration/install-using-nuget

I have subsequently updated the necessary references.

I already had the R2 2022 SP1 version installed. However, based on your advice, I have uninstalled and downloaded and reinstalled it, but it is still the same version.

If I'm not mistaken, this process that you advise me does not work for internals builds (ReleRelease R2 2022 SP1 LIB 2022.2.711). it is right?

Hi, Jaime,

The following article demonstrates how to download the LIB: https://docs.telerik.com/devtools/winforms/installation-and-upgrades/latest-internal-builds

Then, you will need to update the project references with the ones coming from the LIB: https://docs.telerik.com/devtools/winforms/installation-and-upgrades/updating-assemblies-in-a-project

However, a better option is to install directly the R2 2022 SP1 version. Make sure that any older version of the Telerik UI for WinForms suite is firstly uninstalled.

Could you tell me when the update is scheduled?

A very big problem related to this bug is that you cannot minimize the window. I have temporarily disabled the minimize button, but the window can be minimized when the Windows taskbar icon is clicked, causing a CTD that I don't know how to avoid.

Any suggestion?
