I am currently unable to upload any avatar from my account

I am currently unable to upload any avatar from my account, even when using a completely new Unity project with the latest VRCSDK3 (2.4.4) – Avatars package.

I have tried the following steps:

-Created a new Unity project from scratch.

-Installed the latest VRCSDK3 – Avatars package.

-Cleared Library and Temp folders.

-Re-imported all assets and attempted to upload.

Despite these efforts, every attempt results in the following error:

UnityPackage: Model failed validation, returning anyway: Error writing the following fields: assetVersion, created_at, unitySortNumber UnityEngine.Debug:LogWarning (object) VRC.Core.API:CreateFromJson<VRC.Core.ApiAvatar/UnityPackage> (System.Collections.Generic.IReadOnlyDictionary2<string, BestHTTP.JSON.Json/Token>) System.Reflection.MethodBase:Invoke (object,object) VRC.Core.ApiModel:ParseModel (System.Type,System.Collections.Generic.IReadOnlyDictionary2<string, BestHTTP.JSON.Json/Token>,object&) VRC.Core.ApiModel:TryWriteConvert (System.Type,BestHTTP.JSON.Json/Token&,object&) VRC.Core.ApiModel:ParseList (System.Type,System.Collections.Generic.IReadOnlyList1<BestHTTP.JSON.Json/Token>,object&) VRC.Core.ApiModel:TryWriteConvert (System.Type,BestHTTP.JSON.Json/Token&,object&) VRC.Core.ApiModel:WriteField (string,BestHTTP.JSON.Json/Token) VRC.Core.ApiAvatar:WriteField (string,BestHTTP.JSON.Json/Token) VRC.Core.ApiModel:SetApiFieldsFromJson (System.Collections.Generic.IReadOnlyDictionary2<string, BestHTTP.JSON.Json/Token>,string&) VRC.Core.ApiAvatar:SetApiFieldsFromJson (System.Collections.Generic.IReadOnlyDictionary2<string, BestHTTP.JSON.Json/Token>,string&) VRC.Core.API:ConvertJsonListToModelList<VRC.Core.ApiAvatar> (System.Collections.Generic.IReadOnlyList1,bool&) VRC.Core.ApiModelListContainer1<VRC.Core.ApiAvatar>:Validate (bool,System.Func1<byte>,System.Func1) VRC.Core.ApiContainer:OnComplete (bool,int,string,System.Func1<byte>,System.Func1,single) VRC.Core.APIResponseHandler/d__5:MoveNext () Cysharp.Threading.Tasks.CompilerServices.AsyncUniTaskVoid1<VRC.Core.APIResponseHandler/d__5>:Run () (at ./Packages/com.vrchat.base/Runtime/VRCSDK/Plugins/UniTask/Runtime/CompilerServices/StateMachineRunner.cs:104) Cysharp.Threading.Tasks.SwitchToThreadPoolAwaitable/Awaiter:Callback (object) (at ./Packages/com.vrchat.base/Runtime/VRCSDK/Plugins/UniTask/Runtime/UniTask.Threading.cs:218) System.Threading._ThreadPoolWaitCallback:PerformWaitCallback ()

Thank you very much for your assistance.

DirectoryNotFoundException: Could not find a part of the path ‘C:\Users\supan\AppData\LocalLow\VRChat\VRChat\Avatars’

That error is likely causing any issues afterwards.
