Using PnP PowerShell along with Graph is raising this error "Could not load type 'Microsoft.Graph.Authentication.AzureIdentityAccessTokenProvider'"

[mvcsharepointdev]

I have an azure function which is based on PowerShell, here is the local.settings.json file:-

{
  "IsEncrypted": false,
  "Values": {
    "FUNCTIONS_WORKER_RUNTIME": "powershell",
    "FUNCTIONS_WORKER_RUNTIME_VERSION": "7.4",
    "AzureWebJobsStorage": "UseDevelopmentStorage=true"
  }
}

and i have this code , to get all the items from a sharepoint list named "Emails" and remove the users from all their assigned groups:

# Input bindings are passed in via param block.
param($Timer)
# Get the current universal time in the default string format.
$currentUTCtime = (Get-Date).ToUniversalTime()

# The 'IsPastDue' property is 'true' when the current function invocation is later than scheduled.
if ($Timer.IsPastDue) {
    Write-Host "PowerShell timer is running late!"
}

# Write an information log with the current time.
Write-Host "PowerShell timer trigger function ran! TIME: $currentUTCtime"
# Connect to Microsoft Graph with required delegated scopes

Import-Module PnP.PowerShell
Write-Host "Start to connect to SharePoint"
$siteUrl = "https://****.sharepoint.com/sites/DemoCopilot"

# Get all items from the 'emails' list

$items = Get-PnPListItem -List "emails"

Import-Module Microsoft.Graph.Authentication

foreach ($item in $items) {

$userList = Get-MgUser -Filter "mail eq '$userEmail' or userPrincipalName eq '$userEmail'"  -ConsistencyLevel eventual -All -Property Id, DisplayName, UserPrincipalName, Mail
 Write-Host "Get-MgUser completed"
$userObj = $userList | Select-Object -First 1

if (-not $userObj) {
    Write-Host "User $userEmail not found in Microsoft Graph. Skipping AAD removal."
} elseif (-not $userObj.Id) {
    Write-Host "User objectId missing even after lookup. Skipping AAD removal."
} else {
    Write-Host "Found user: $($userObj.DisplayName) ($($userObj.UserPrincipalName))"

    $groups = Get-MgUserMemberOf -UserId $userObj.Id -All
    $groupsAsOwner = Get-MgUserOwnedObject -UserId $userObj.Id -All


    foreach ($group in $groups) {
        if ($group.AdditionalProperties.'@odata.type' -ne '#microsoft.graph.group') {
            continue
        }

        $groupId = $group.Id
        $groupName = $group.AdditionalProperties.DisplayName

        if (-not $groupId) {
            Write-Host "Skipping group with empty ID"
            continue
        }

        $fullGroup = Get-MgGroup -GroupId $groupId

        if ($fullGroup.GroupTypes -contains "DynamicMembership") {
            Write-Host "Skipping dynamic group: ${groupName}"
            continue
        }

        # Remove as MEMBER
        try {
            Remove-MgGroupMemberByRef -GroupId $groupId -DirectoryObjectId $userObj.Id -ErrorAction Stop
            Write-Host "Removed as MEMBER from ${groupName}"
        }
        catch {
            Write-Host "Failed MEMBER removal from ${groupName}: $($_.Exception.Message)"
        }}
foreach ($group2 in $groupsAsOwner) {
$groupId2 = $group2.Id
$groupName2 = $group2.AdditionalProperties.DisplayName
        # Remove as OWNER
        try {
            Remove-MgGroupOwnerByRef -GroupId $groupId2 -DirectoryObjectId $userObj.Id -ErrorAction Stop
            Write-Host "Removed as OWNER from ${groupName2}"
        }
        catch {
            Write-Host "Failed OWNER removal from ${groupName2}: $($_.Exception.Message)"
        }
    }
    }

# --- PART 2: Exchange Distribution Groups + Mail-enabled Security Groups ---

Write-Host "Start Get-DistributionGroup"

Write-Host "completed Get-DistributionGroup"

foreach ($dl in $dlGroups) {
    try {
        # Remove as MEMBER
        $members = Get-DistributionGroupMember -Identity $dl.Identity -ResultSize Unlimited
        $memberMatch = $members | Where-Object { $_.PrimarySmtpAddress -ieq $userEmail }

        if ($memberMatch) {
            Remove-DistributionGroupMember -Identity $dl.Identity -Member $userEmail -BypassSecurityGroupManagerCheck -Confirm:$false
            Write-Host "Removed as MEMBER from Exchange group: $($dl.DisplayName)"
        }

        # Remove as OWNER
        # $owners = (Get-DistributionGroup -Identity $dl.Identity).ManagedBy
        $owners = (Get-DistributionGroup -Identity $dl.Identity).ManagedBy | Foreach-Object { Get-Mailbox $_ }
        $ownerMatch = $owners | Where-Object { $_.PrimarySmtpAddress -ieq $userEmail }

        if ($ownerMatch) {
            Set-DistributionGroup -Identity $dl.Identity -ManagedBy @{ Remove = "$userEmail" }
            Write-Host "Removed as OWNER from Exchange group: $($dl.DisplayName)"
        }
    }
    catch {
        Write-Host "Failed Exchange removal for group: $($dl.DisplayName) - $($_.Exception.Message)"
    }
}

}
  

But i got this error when the function runs:-
