Unable to apply user preferences

[shot-codes]

I'm trying to apply user settings for the package as per the documentation via Preferences → Package Settings → A File Icon → Settings. I try to change the icon size with the following sublime-settings file:

// A File Icon Preferences – User
// ================================================================
{
	"size": 4
}

The change does not take effect and there is a pop up with the message Error loading syntax file "Packages/zzz A File Icon zzz/aliases/JSON (Sublime).sublime-syntax": Unable to read Packages/zzz A File Icon zzz/aliases/JSON (Sublime).sublime-syntax

Expected Behavior

I expect that the icon size changes.

Current Behavior

There is no change and there is a pop up with an error message.

Environment

I can't seem to find the environment command via the command palette, nor the settings menu.
I am on MacOS Big Sur, and Sublime Text build 4113
output from the console:

reloading settings Packages/User/A File Icon.sublime-settings
ignored packages updated to: ["Vintage", "zzz A File Icon zzz"]
reloading settings Packages/User/Preferences.sublime-settings
error: Error loading syntax file "Packages/zzz A File Icon zzz/aliases/JSON (Sublime).sublime-syntax": Unable to read Packages/zzz A File Icon zzz/aliases/JSON (Sublime).sublime-syntax

The setting is meant to tweak icon appeareance of themes, which are not known to support A File Icon, such as Default/Adaptive.

A File Icon only applies least required patch to themes which claim to support A File Icon, such as AYU and Theme - DAneo. The "size" is not part of it, atm.

The error message Error loading syntax file ... is caused by the mensioned syntax being removed and recreated once A File Icon settings change while a view with such a syntax is still open (the settings).

Enabling/Disabling aliases is already handled so it should be possible to avoid it in this situation as well.

Ah okay thanks @deathaxe. I am indeed using Ayu theme together with A File Icon. If I understand correctly then, there isn't an ability to change the size of the icons provided by A File Icon?

[deathaxe]

Not at the moment, no. It shouldn't be a big deal to change that though.

This error message can be ignored. It's a false positive unrelated with this issue.
