Hey guys, frequent searcher of this forum but this issue is the first which has me completely stuck and not able to solve with lots of Googling.

MY MM prompted an update last week, which I did following the update guidance on the main builder site. Part way through the update failed, I had to go away for the bank holiday here in the UK and I’m now picking it back up.

As per the title I launch the magicmirror in terminal using pm2 start mm.sh (it’s always worked) it says it’s done but then the MM never actually launches.

when I check the pm2 logs I get an error around a directory no being empty and the node_module engine.io needing renaming.
any thoughts on sorting this? I don’t know if this is just the first hurdle or the only reason the MM is no longer launching.
I don’t have a programming background so please be gentle.
Cheers.
