                        [Feature] MsalCacheHelper does not work with 100+ threads
Hi, we have a customer complaining on the following error when running different threads on the same process, using out .NET SDK:

We are using MsalCacheHelper for dealing with this file, Register to the TokenCache when creating PublicClientApplication on AuthN request
Which version of MSAL.NET are you using? Microsoft.Identity.Client.Extensions.Msal 2.18.9
Platform Net Framework 4.7.2
What authentication flow has the issue? Kusto .NET SDK user prompt.
Is this a new or existing app? Already in production, probably not many customers are using multi-threads with UserPromptAuthentication.
