@kondef you can see my topic where @sdetweil helped me to solve issues.

At this time, my mirror works again, excepted the Remote-Control module.
Don’t worry, your mirror will come back well soon also for you ;-)

Rebuild is done for the Assistant. The MM is launnching again. I didn’t try to activate it by saying “Jarvis” (everyone is sleeping at home).

I put PIR module ON, black screen again, and still this error :

[2020-04-01 23:30:25.054] [ERROR] WARNING! Could not load config file. Starting with default configuration. Error found: Error: The module ‘/home/pi/MagicMirror/modules/MMM-PIR-Sensor/node_modules/epoll/build/Release/epoll.node’
was compiled against a different Node.js version using
NODE_MODULE_VERSION 64. This version of Node.js requires
NODE_MODULE_VERSION 73. Please try re-compiling or re-installing
the module (for instance, using npm rebuild or npm install).

EDIT : So I did a “npm install” into the MMM-PIR-Sensor folder, and now it works again.
A very big THANK YOU to YOU !!!

Ok, thanks for your help so far.
The rebuilding is not done yet ; still running.

Yes I disabled it.
Can I run a new Putty window while the rebuild of Assistant is running, to check ?

It is still running, but nothing changed into the terminal.
After the command “npm install --save-dev electron-rebuild” I had this message :

• electron-rebuild@1.10.1
  updated 2 packages and audited 822 packages in 16.302s

3 packages are looking for funding
run npm fund for details

found 9 low severity vulnerabilities
run npm audit fix to fix them, or npm audit for details

Should I run “npm fund” and “npm audit fix” before launching the second command ?

Ok I understand.
I saw a message on the Remote Control module github and it seams there is also a problem with it after the MMM update.

My MagicMirror was running as a charm till this update. I saw the alert on the MM screen so I did it… what a shame

Don’t know yet.
Did I do something wrong with the update ?
Everything seams to be broken…

Anyway, thank you very much for your precious help and sorry for my poor english (I’m from France)

yep assistant… same problem as hotword… incompatible binary versions

Then, you need to rebuild grpc module for electron of MagicMirror.

npm install --save-dev electron-rebuild
./node_modules/.bin/electron-rebuild

For the last command, it is very long to achieve ; 5 minutes that it runs.
It’s written : Building module : grpc, Completed: 0

Now it is the Jarvis Assitant :
