ERROR! Could not validate main module js file.

[fering3]

Getting the following error when loading MM. The calendars never load on electron (on the Pi), however when loading from an external browser, the calendars load without a problem. Could be an issue with the node version, but i have updated, and it had no effect.

I doubt MM has downgraded its node version of electron for some reason. Unfortunately, ‘async function’ is not working on the lower version of node. I think that is the reason for this issue. I’ll check and patch this for some time. Sorry, I should do my job first before this. Plz wait for a while.

I removed async from source. I hope this could be the solution.
