TabbySSH can't be opened by multiple users on a Remote Desktop server

[Shane1390]

Describe the problem:
On a Remote Desktop Server deployment (tested on Windows Server 2019/2022), no more than 1 non-Administrator and 1 Administrator user can have Tabby opened. When other users attempt to open the application, 2 processes will spawn and then terminate, until another user has closed Tabby.

To Reproduce:

• On a Windows Server 2019/2022 non-VDI deployment
• Install TabbySSH
• Under 2 non-Administrator users, attempt to open TabbySSH
  • The second user will fail here
• Observe Task Manager
• Run TabbySSH as Administrator
  • A second instance will open in this case
• As a separate Administrator user, run TabbySSH as Administrator
  • The second Administrator user will fail here
• Observe Task Manager

We have tested this outcome with the portable installation of Tabby (in both %PROGRAMFILES% and %LOCALAPPDATA%), as well as user-based and machine-wide installations of Tabby. We've also tested creating several copies of the Tabby portable files and editing the NTFS permissions to explicitly block other users from viewing the contents, to no avail.

Are there some arguments we can pass to Tabby, to allow multiple instances on the same machine?
