Unable to do any operations on electron app after the window gets loaded

[harishpatha]

I have launched the electron app with spectronclient and performing some test operations on it.
Electron version : ^6.0.8
Spectron version : ^8.0.0

code:
app = new Application({
path: "C:\Users\<PATH_TO_APP>\electron.exe",
quitTimeout: 5000,
startTimeout: 10000,
waitTimeout: 10000
});
await app.start();
await app.client.waitUntilWindowLoaded();
await app.client.click(".//div[@Class = 'user-balance']");
await app.client.click(".//vn-menu-item[contains(.,'Settings')]");

This launches my application and do 1 or 2 clicks and then it stucks there and doesnt proceed further.
can you please help if anyone faced this issue before?

Note:i have tried client.selectWindow() and browserWindow().focus also. No luck.
