Issue
Connecting to PnP module using the Connect-PnPOnline command is throwing an unexpected error. We could observe this is an intermittent issue, but now it is occurring too frequently.

Expected behavior

For connecting to PnP module, as mentioned in the documentation we have Imported the PnP module and by using the Connect-PnPOnline, it should connect to Sharepoint tenant
Environment:
Azure Powershell Function
Powershell version: 7.2
PnP module version: 2.3.0

Import-Module "D:\home\site\wwwroot\Modules\pnp.powershell.2.3.0\PnP.PowerShell.psd1";
Connect-PnPOnline -Url $sharepointAdminUrl -ClientId $appId -Tenant $domain -Thumbprint $certificateThumbprint -ErrorAction:Stop
The above should succesfully connect to Sharepoint

Actual behavior

When connecting to PnP, the below error is being popped up frequently
"errorStackTrace": " at PnP.PowerShell.Commands.Base.PnPConnection.CreateWithCert(Uri url, String clientId, String tenant, String tenantAdminUrl, AzureEnvironment azureEnvironment, X509Certificate2 certificate, Boolean certificateFromFile)\r\n at PnP.PowerShell.Commands.Base.ConnectOnline.ConnectAppOnlyWithCertificate() in c:\build\src\Commands

Steps to reproduce behavior

$sharepointAdminUrl = "https:"
$appId = "xxx" // Application registered in the azure portal with all the necessary permisiions mentioned
$certificateThumbprint = "xxx" // thumbprint of the above applicationId
$domain="xxx.com" // domain of our organization

Hi @gautamdsheth,
The above issue is intermittent, we also use our Azure function platform to run the MS PowerShell EXO and Teams modules as well, if these modules are running simultaneously, the dll loading conflicts may occur, we need something like ALC support for PnP module, I tried the latest nightly builds but still the same issue. Please advise.
