Plugin error from fragment-insertion:
Sorry but providing support for these is going to be very difficult for all of us who are attending the workshop, your best bet is to try and recruit help after or simply grab the output files for problematic steps from here: https://docs.qiime2.org/2020.8/tutorials/pd-mice/
that way you can continue along
@ad2459, like @Mehrbod_Estaki suggested, probably best to just download the output files so you can keep up.
When you have time to troubleshoot this later, though, you might look at what resources you have allocated to your VM. You may be running out of memory (RAM).
A forum search will turn up other questions that troubleshoot out of memory (OOM) errors in VMs - you may find useful resources there.
Exit code 134 refers to memory allocation issues. I am pretty sure you have to increase the amount of RAM assigned to the VM in order to get this computation done.
