Cannot select PrusaLink for new physical printer

[m1dnight]

Description of the bug

I have the newest version of PrusaSlicer (see details below) and firmware version 6.0.4+14924 on my MK4.

I wanted to add a new physical printer without input shaping, but I can only select PrusaConnect as the option to connect to the printer. PrusaLink is missing.

When I try to add a new physical printer with the input shaper profile, I do have the option to select PrusaLink to connect the printer.

See the attached screenshots.

The same for MINI.
Moreover, when selecting OctoPrint for non-IS profile, the Slicer

• behaves during the test like it was PrusaConnect
• After saving the physical printer, it behaves like it was PrusaConnect selected (luckily it prints through octoPrint properly)
• after entering the edit of the physical printer, the chosen HostType is PrusaConnect (instead of OctoPrint).

Same for me, PrusaLink no longer shows up in the host type dropdown. (see image.) I have to export gcode to desktop then upload+print from the Prusa Connect tab in prusaslicer. Selecting host type PrusaConnect always gives me a forbidden error, but thats a different issue.
