Error: Calls to "AssetDatabase.SaveAssets" are restricted during asset importing. UnityEngine.StackTraceUtility:ExtractStackTrace ()

Hello,

I am getting this error out of the box:

Calls to "AssetDatabase.SaveAssets" are restricted during asset importing. 
UnityEngine.StackTraceUtility:ExtractStackTrace ()
Unity.AutoLOD.ModelImporterLODGenerator:SaveLODData (string,Unity.AutoLOD.LODData,System.Collections.Generic.List`1<Unity.AutoLOD.IMeshLOD>,System.Collections.Generic.HashSet`1<int>) (at ./Library/PackageCache/com.yvesalbuquerque.autolod@2480335ff9/Editor/ModelImporterLODGenerator.cs:366)
Unity.AutoLOD.ModelImporterLODGenerator:OnPostprocessModel (UnityEngine.GameObject) (at ./Library/PackageCache/com.yvesalbuquerque.autolod@2480335ff9/Editor/ModelImporterLODGenerator.cs:82)
UnityEngine.GUIUtility:ProcessEvent (int,intptr,bool&)

Any idea how to fix?

Not sure if Unity changed things around or what but it seems like this same issue happens in another use case that they fixed in Unity 6. Seems like they are pushing people to upgrade to 6 for the run-time fee, so I haven't even bothered to test if 6 solves this issue. I am using 2023.2.20f1.

I tried other ways of moving when the save occurs, but I ran into issues with static classes, lack of Editor Coroutines (didn't want to install the new package) as well as it just breaking everything else. So this was the best fix I could do.

I band-aided this by replacing the line in (ModelImporterLODGenerator/SaveLODData:365)
AssetDatabase.SaveAssets();
with:
AssetDatabase.SaveAssetIfDirty(lodData);

It seems to run fine without doing this while still getting the error by simply re-importing the models a second time to get the updated LODs. This fix however seems to make only one re-import (as intended) work again. I have not fully figured out if this is the case however - more testing is needed.
