Problems starting Universal.Server.exe v 1.2.1

PowerShell Universal
1

I can´t start the universal server. It crashes with the following error:
Unhandled exception. System.Exception: Error while deserializing. A parameter cannot be found that matches parameter name ‘PowerShellVersion’.
at UniversalAutomation.PowerShellSerializer1.Deserialize(String script, IDatabase database) at UniversalAutomation.Services.UniversalConfigurationService.Read[T](Func2 includes)
at UniversalAutomation.Services.UniversalConfigurationService.SyncAsync()
at UniversalAutomation.StartupService.StartAsync(CancellationToken cancellationToken)
at Microsoft.Extensions.Hosting.Internal.Host.StartAsync(CancellationToken cancellationToken)
at Microsoft.Extensions.Hosting.HostingAbstractionsHostExtensions.RunAsync(IHost host, CancellationToken token)
at Microsoft.Extensions.Hosting.HostingAbstractionsHostExtensions.RunAsync(IHost host, CancellationToken token)
at Microsoft.Extensions.Hosting.HostingAbstractionsHostExtensions.Run(IHost host)
at Universal.Server.Program.Main(String[] args)

I have Powershell 7.0.2 installed.

I have probably done something wrong, but I don’t know what. Pleas help.

Kind regards
Peter

Can you grab a log from C:\ProgramData\PowerShellUniversal?

I’d like to see which file it’s failing to load.
