There is a “hotfix” build available, that can be requested from the FSL support. Quote from the support forum: “A Hotfix build is now available for this, but is being released more slowly and to early adopters first to ensure higher code quality. Support has been asked to give the release to any customers hitting this issue. Please open a support ticket and let them know that you have hit the 1909 deadlock issue, and they should get you a link to the fix. We hope that some testing improvements, and an early adopter program will help us prevent this type of regression in the future”
