ClipboardFusion (CF) keeps clearing its clipboard history automatically.
Details:

Uncertain Cause: Not sure if this is due to CF settings, a Windows conflict, or interference from another application.

I've also created a small powershell script to monitor and log events:

# Load necessary assemblies
Add-Type -AssemblyName System.Windows.Forms
Add-Type -AssemblyName PresentationFramework
Add-Type -AssemblyName PresentationCore
Add-Type -AssemblyName WindowsBase

# Define paths
$logFile = "$env:APPDATA\ClipboardClearMonitor.log"

# Ensure log file exists
if (-not (Test-Path $logFile)) {
    New-Item -ItemType File -Path $logFile -Force | Out-Null
}

# Log script start
$timestamp = Get-Date -Format "yyyy-MM-dd HH:mm:ss"
Add-Content -Path $logFile -Value "$timestamp - Script started."

# Display the log file path to the user
Write-Host "------------------------------------------------------------" -ForegroundColor Cyan
Write-Host "Clipboard monitoring started." -ForegroundColor Green
Write-Host "Log file: $logFile" -ForegroundColor Yellow
Write-Host "This window will display all clipboard changes." -ForegroundColor Green
Write-Host "------------------------------------------------------------" -ForegroundColor Cyan

# Notification function
function Show-WindowsNotification {
    param ([string]$message)
    try {
        [System.Windows.Forms.NotifyIcon]$n = New-Object System.Windows.Forms.NotifyIcon
        $n.Icon = [System.Drawing.SystemIcons]::Information
        $n.BalloonTipTitle = "Clipboard Alert"
        $n.BalloonTipText = $message
        $n.Visible = $true
        $n.ShowBalloonTip(10000)
        Start-Sleep -Seconds 10
        $n.Dispose()
    } catch {
        Write-Host "$(Get-Date -Format 'yyyy-MM-dd HH:mm:ss') - Notification error: $($_.Exception.Message)" -ForegroundColor Red
    }
}

# Clipboard reader
function Get-ClipboardContentSummary {
    try {
        $dataObj = [Windows.Forms.Clipboard]::GetDataObject()
        if ($dataObj -eq $null) {
            return "<null>"
        }
        $formats = $dataObj.GetFormats()
        if ($formats.Count -eq 0) {
            return "<empty>"
        }
        return ($formats -join ", ")
    } catch {
        $err = $_.Exception.Message
        $timestamp = Get-Date -Format "yyyy-MM-dd HH:mm:ss"
        $logEntry = "$timestamp - Clipboard access error: $err"
        Add-Content -Path $logFile -Value $logEntry
        Write-Host $logEntry -ForegroundColor Red
        return "<unreadable>"
    }
}

try {
    $lastClipboardSummary = Get-ClipboardContentSummary
    while ($true) {
        Start-Sleep -Seconds 1
        $currentSummary = Get-ClipboardContentSummary

        if ($currentSummary -ne $lastClipboardSummary) {
            $timestamp = Get-Date -Format "yyyy-MM-dd HH:mm:ss"
            $logEntry = "$timestamp - Clipboard changed: $lastClipboardSummary â†’ $currentSummary"
            Add-Content -Path $logFile -Value $logEntry
            Write-Host $logEntry

            if ($currentSummary -eq "<empty>" -or $currentSummary -eq "<null>" -or $currentSummary -eq "<unreadable>") {
                Show-WindowsNotification "Clipboard was cleared or inaccessible."
            }

            $lastClipboardSummary = $currentSummary
        }
    }
} catch {
    $timestamp = Get-Date -Format "yyyy-MM-dd HH:mm:ss"
    $logEntry = "$timestamp - FATAL ERROR: $($_.Exception.Message)"
    Add-Content -Path $logFile -Value $logEntry
    Write-Host $logEntry -ForegroundColor Red
    Pause
}

Pause

Output to log:

ClipboardClearMonitor.log
This window will display all clipboard changes.

I'm unable to locate the culprit.

This issue began maybe a week or so ago, uncertain though, it could be a WU KB5062554 and KB5063706 recent updates. I've not uninstalled these yet.

I don’t like using WKey+V, the window doesn’t stay open, unlike ClipboardFusion, which works great.

Can you send me a screenshot of the ClipboardFusion Settings > Application Exceptions > Default Copy Settings Edit window?

Removed KB5062554 and the issue has stopped.

KB5062554 likely modified or interfered with clipc.dll or system clipboard notification chains, causing clipboard flushing of third-party apps.

Hopefully you guys can get a fix out soon. With a little more digging KB5062554 has issues.
