Is there an existing issue for this problem?

I have searched the existing issues

OrcaSlicer Version

2.3.2

Operating System (OS)

Windows

OS Version

Windows 11

Additional system information

No response

Printer

Bambu A1

How to reproduce

Same issue, different ways, always begining with;
Have OrcaSlicer open, then;
attempt to open .stl or .3mf file or;
on printables.com, click slice with OrcaSlicer or;
in Fusion360, use the print utility to export to stl/3mf and auto open in OrcaSlicer

Actual results

Nothing happens. The program functions as requested, whether it be printables or fusion (or even windows desktop when trying to open stl/3mf)

Expected results

After clicking whatever button or attempting to open whatever file, OrcaSlicer (whilst already open) should auto import/place whatever stl/3mf you wanted imported into current instance

Checklist of files to include

Log file
Project file

Anything else?

According to log, Orca believes I want a new instance rather than place it into my current instance like the last nightly version. No settings were changed between versions. I've attached screenshots of my current settings

EDIT: Added log_iotc.zip
