<Updated Etrecheck Report with Full Disk Access.log>
Several issues from your Etrecheck report:
Antivirus software: Apple, Avira, and Malwarebytes
Red flag here for Avira anti-virus. That should be 100% UNINSTALLED using an uninstaller from the provider. You may have to search for leftover remnants from that software.
Malwarebytes is likely ok but should be uninstalled also to try to provide a clean reference system. It can be reinstalled later. But I suggest NOT using its VPN (or any VPN) and also turning off its automatic background checking.
System Extensions:
AdBlock VPN Tunnel - version 4.0.6 (App Store - installed 2026-08-20)
Application: /Applications/AdBlock.app - version 4.0.6 (App Store - installed 2026-09-06)
Description: AdBlock requires this extension to create a VPN tunnel for ad blocking.
Another VPN, should be completely UNINSTALLED.
Malwarebytes Engine - version 5.27.1 (Malwarebytes Corporation - installed 2026-10-01)
Application: /Applications/Malwarebytes.app - version 5.27.1 (Malwarebytes Corporation - installed 2026-10-01)
Description: The Malwarebytes Engine extension manages your connection to the Malwarebytes VPN service.
The VPN here should also be deactivated. I don't know how it is mechanized so to be safe, completely uninstall Malwarebytes for now, it can be re-installed later, but I suggest without its VPN and without automatic background checking. Malwarebytes even in minimal mode scans every day, you will be quite safe without all that other stuff.
DuckDuckGo VPN Network Extension - version 1.210.0 (Duck Duck Go, Inc. - installed 2026-10-07)
Application: /Applications/DuckDuckGo.app/Contents/Library/LoginItems/DuckDuckGo VPN.app - version 1.210.0 (Duck Duck Go, Inc. - installed 2026-10-07)
Description: DuckDuckGo VPN
So now I count at least three VPNs. Even if not active or running, these multiple installations can create conflicts.
All VPNs should be completely uninstalled (unless required and custom configured by an employer or school). These interfere with all kinds of network/internet functions on Macs and lo and behold, you are experiencing iCloud issues with syncing and with FindMyMac.
IMPORTANT: you are experiencing anomalies in your network and connection to the internet ... e.g. Contacts not syncing and other issues (Find My Mac not working). All these VPNs might be falling over one another and certainly interfering with normal Mac network and system operations. Plus that anti-virus on top of it all, I am not surprised you are being blocked somehow in some of your cloud functionalities.
Kernel Extensions:
/Library/Extensions
FileAccessControl.kext - com.avira.kext.FileAccessControl (1.2.5 - SDK 10.9)
Huge problem having anti-virus like this on a Mac. It might be blocking your icloud functions or somehow combining with all those VPNs to interfere.
Other stuff still showing in the Etrecheck report, these things are still present and can impact functionality even when not loaded. All of these items should be 100% completely uninstalled and removed:
User Login Items:
[Not Loaded] CleanMyMac_5_HealthMonitor (MacPaw Way Ltd - installed 2026-09-25)
Modern Login Item
/Applications/CleanMyMac_5.app/Contents/Library/LoginItems/CleanMyMac_5_HealthMonitor.app
[Not Loaded] CleanMyMac_5_Menu (MacPaw Way Ltd - installed 2026-09-25)
Modern Login Item
/Applications/CleanMyMac_5.app/Contents/Library/LoginItems/CleanMyMac_5_Menu.app
[Not Loaded] DuckDuckGo Personal Information Removal (Duck Duck Go, Inc. - installed 2026-10-07)
Modern Login Item
/Applications/DuckDuckGo.app/Contents/Library/LoginItems/DuckDuckGo Personal Information Removal.app
[Not Loaded] DuckDuckGo VPN (Duck Duck Go, Inc. - installed 2026-10-07)
Modern Login Item
/Applications/DuckDuckGo.app/Contents/Library/LoginItems/DuckDuckGo VPN.app
CleanMyMac is still active! This can be poison for the macOS. See below:
Plugins:
[Loaded] CleanMyMac_5_AppIntentsExtension - /Applications/CleanMyMac_5.app
[Loaded] Intents - /Applications/WhatsApp.app
Finder sync extensions:
[Not Loaded] CleanMyMac_5_FinderSyncExtension - /Applications/CleanMyMac_5.app
Ancient internet plug ins, probably not the cause but who knows, these are non-functional and should be uninstalled:
Internet Plug-ins:
RL Secure Plug-In Layer: (? - installed 2014-02-21)
OfficeLiveBrowserPlugin: 12.3.6 (? - installed 2013-03-19)
Silverlight: 5.1.50428.0 (? - installed 2016-08-03)
Very slow read and write disk speeds for an SSD. Should be 2x as fast as what you are getting. This could be due to interference from the antivirus or real time checking of Malwarebytes or some combination of those questionable extensions, VPNs, etc. I pointed out above, including the pieces that are left over from CleanMyMac.
