No error but Runtime won't start on MTP1000 panel after TIA V20 update

My project in TIA Portal is also set to version 20.0.0.2. However, when I load the project to the panel, the initialization process starts, but the runtime itself does not launch — there is no error message displayed. Interestingly, the web clients do start and function, but the local runtime interface on the panel does not appear. When I connected to the web client, I saw many errors in the alarm Viewer : Certificate for signing not found in the certificate store The VisualCoreService manager is not connected For context, this project was originally developed in version 19. I migrated both the project and the operating system to version 20.0.0.2 in order to configure the network drive. Has anyone encountered this issue? Any ideas on how to resolve it? Thanks in advance!

Using the Trace Viewer may provide some clues, but it will be time-consuming, especially if you are unfamiliar with the trace messages produced by the system. Therefore, it would be better to have a Siemens developer perform this analysis. I suggest creating a support request. Kind regards Stefan

This version allows me to start the runtime and use the network drive successfully. However, there's still one issue: the "Audit queries" folder does not get saved when I restart the runtime, while in the version V20.0.0.2 the runtime retain the path of folder Audit Queries

Reporting it to Siemens by creating a support request will make the development team aware of the issue. Kind regards Stefan
