Just updated my desktop app to and am getting runtime errors pretty consistently on plugins I’ve built that were previously running fine. 

Here’s the console error:

jsvm-cpp.wasm.br:0x23113 Uncaught (in promise) RuntimeError: memory access out of bounds
    at jsvm-cpp.wasm.br:0x23113
    at jsvm-cpp.wasm.br:0x3a412

Once I start seeing this error, the plugin refuses to open until I restart the app. After it restarts, I can open the app a few times before the error starts back up again.

The issue seems to be with loading fonts. If I remove all the font code, the plugin opens without complaint. Something has changed in the latest update that seems to be causing this issue.
 

const setup = async () => {

  console.log('Loading the necessary fonts... ');



  await figma.loadFontAsync({ family: 'Sun Life Sans', style: 'Regular' });

  await figma.loadFontAsync({ family: 'Sun Life Sans', style: 'Medium' });

  await figma.loadFontAsync({ family: 'Sun Life Sans', style: 'Bold' });

  await figma.loadFontAsync({ family: 'Sun Life New Text', style: 'Regular' });

  await figma.loadFontAsync({ family: 'Sun Life New Text', style: 'Bold' });

  await figma.loadFontAsync({ family: 'Sun Life New Text', style: 'Italic' });

  await figma.loadFontAsync({ family: 'Sun Life New Display', style: 'Bold' });

  await figma.loadFontAsync({ family: 'Sun Life New Display', style: 'Regular' });

  await figma.loadFontAsync({ family: 'Inter', style: 'Regular' });

  await figma.loadFontAsync({ family: 'Agenda', style: 'Bold' });

  await figma.loadFontAsync({ family: 'Agenda', style: 'Medium' });

  await figma.loadFontAsync({ family: 'Agenda Light', style: 'Regular' });

};



setup().then(async () => {

  // Show the UI

  figma.showUI(__html__, { width: 450, height: 600 });

});



figma.ui.onmessage = async (msg) => {

  if (blah blah) {

    // app logic

  } else {

    figma.closePlugin();

  }

};
