cTrader Doesn't work/start in first few try

So what happens is, after clicking on desktop shortcut, cTrader flash screen comes for short time & disappears in few second. Than main window of cTrader doesn't appear. So, I try starting again & same thing happens. After trying few more times, its starts ok(flash screen appear for longer time & main windows starts ok). So, basically I have to click on shortcut icon 3-4 times to run program.

In my system, this happened with cTrader v4.4.17,v4.4.19 & now with latest update v4.5.1. cTrader version 4.2.22 work perfectly. I have tried uninstalling both and keeping one at time and so on. but nothing seems to solve this issue with cTrader cross-broker version.

if there is way to get log, I can give it to you, just explain process to me, and I will send it. I can also share screen recording if you want.

Please help me with this.

p.s. I have sent report with Ctrl+Alt+Shift+T shortcut function.
