Flows not shown in prefect UI on self-hosted server

Hi,

Our Prefect server UI does not show any flows under the “flows” section. Clicking on a flow from “deployments” section also leads to same issue.

The following error message is shown in the web console:

index-af913952.js:1 TypeError: r.value.at is not a function
at vY.fn (index-af913952.js:123)
at vY.run (index-af913952.js:1)
at rq.get value [as value] (index-af913952.js:1)

at vY.de [as fn] (index-af913952.js:1)
at vY.run (index-af913952.js:1)

The server is running on Windows Server 2022.

Any suggestion regarding this problem?

Thank’s!
