Enabling icon preview of non-standard icon packages hangs intellij

[absar]

Steps to Reproduce

Add font_awesome_flutter to Font packages, press Apply and OK, doing so hangs Intellij forever and afterwards re-opening the project hangs as well, at the bottom of Intellij Checking Icons appears, but it never completes, consuming 90+% CPU on an Intel i7.

The feature was probably developed in: #5595

Which version of font_awesome_flutter are you using? It seems something broke in version 0.9.2 but 0.9.1 works (for me, anyway).

Am using 9.2.0. Facing same issue with 9.1.0

Doesnt work with my custom icons too

I have the same problem with Android 2021.1 and earlier versions. The 'Checking Fonts' process stays running and never ends, completely blocking the IDE with 100% CPU.

We are investigating a different solution for rendering icon previews.

Is there any update?
