Launcher / GameStudio - Unable to start Game Studio when JetBrains Fleet is installed alongside 4.2.1.2442

Release Type: Official Release

Version: 4.2.1.2442

Platform(s): Windows

Describe the bug
When the most recent JetBrains Fleet is installed then Game Studio is unable to start. It does not show any error and logs are not available.

This happens because in IDEInfo Fleet is detected as an installation of Rider, but somehow installationVersion and instanceId is not available and it makes the code in IDEInfo throw an unhandled ArgumentNullException.

    public IDEInfo(Version installationVersion, string displayName, string? programPath, string instanceId, IDEType ideType)
    {
        DisplayName = displayName ?? throw new ArgumentNullException(nameof(displayName));
        InstallationVersion = installationVersion ?? throw new ArgumentNullException(nameof(installationVersion));
        InstanceId = instanceId ?? throw new ArgumentNullException(nameof(instanceId));
        ProgramPath = programPath;
        IDEType = ideType;
    }

Additional context
Add any other context about the problem here.

Start with the IDEInfo constructor and the detection path that identifies JetBrains Fleet as Rider, using the provided ArgumentNullException details as the failure point. Reproduce on Windows with Fleet 1.48.261 and Stride 4.2.1.2442; done means Game Studio starts successfully with Fleet installed and the existing IDE detection behavior remains intact.
