Is there an existing issue for this problem?

I have searched the existing issues

OrcaSlicer Version

2.3.1-alpha

Operating System (OS)

Windows

OS Version

Windows 11 Home

Additional system information

CPU: Intel Core i7 - 10510U @ 1.80GHz
Memory: 16 GB
Display Card: NVIDIA GeForce GTX 1050

Note: The laptop has both Intel integrated graphics and an NVIDIA GTX 1050. It’s possible OrcaSlicer is using the integrated GPU.

Printer

Creality Ender-3 V2 0.4 nozzle

How to reproduce

Boot Windows and log in.
Wait until the system finishes loading (no heavy background tasks).
Open OrcaSlicer (2.3.1-alpha) and wait until it fully loads.
Go to Filament Manager.
Measure the time until the window fully loads.

Actual results

On the first launch after system boot, opening Filament Manager takes about 2 minutes.
The UI does not freeze (window can be moved or closed), but the content loads very slowly.
After the first load, reopening Filament Manager only takes 6–8 seconds (similar to v2.3). It still does even if OrcaSlicer is closed and then reopened.
After restarting the PC, the issue repeats.

Note: If a new Custom Filament is created, the next time opening Filament Manager again takes ~2 minutes.

Expected results

Filament Manager should load in a few seconds (similar to previous versions, ~6–8s), even on first launch.

Anything else?

This behavior started with 2.3.1-alpha (previous version 2.3 did not have this long delay, as long as I can recall).
Checked Windows Task Manager during the delay: CPU, memory, and disk usage remain normal, no noticeable spikes in resource consumption.
