Microsoft Designer is a cloud service that is accessed through the browser or integrated in other Microsoft apps; it is not installed or versioned locally in a way that allows rolling back to an older release on Windows 10 or Windows 11. There is no supported way to install an older version of Designer on a PC.
Designer is provided for personal use with a Microsoft account and is updated by Microsoft on the service side. Issues such as text tools or text boxes not behaving correctly are handled through service updates rather than user-managed installs. The available guidance is to access Designer at https://designer.microsoft.com with a personal Microsoft 365 account and use the current, service-hosted version.
If the issue persists across multiple devices (Windows 10 and Windows 11) using the same service, it indicates a service-side or account-specific problem rather than something that can be fixed by reinstalling or downgrading. In that case, the next step is to use official support channels (for example, via the Help/Feedback options within Designer or the Microsoft account support pages) so the issue can be investigated and addressed in the live service.
There is no documented, supported “older Designer client” to install locally, and no enterprise/alternate channel builds are available for rollback.
