Thanks for the fix. But post this we were facing an issue post electron upgrade.

Error:
/node_modules/electron/dist/Electron.app/Contents/MacOS/Electron exited with signal SIGTRAP
[91253:0529/192908.067019:ERROR:shared_memory_switch.cc(244)] Mach rendezvous failed, terminating process (parent died?)

Because of this our application is getting crashed frequently during testing. We havent faced such errors in previous versions. Attaching the error trace as well
