Hello!
I install fresh Joomla 4.3.4 and VM 4.2.2 or VM 4.2.4 on it. Now if i want to install VM sample data (Reset all Virtuemart tables and do a fresh install with sample data) its ending with error (on attached image). I see this job removes plugin \system\vmloaderpluginupdate and then this job cant end - it need file vmloaderpluginupdate.php in this folder. If i hold this file disabling to delete it then job ends correctly :)
