why do you need to backup the private keys for? Just make sure you have the 12-word seed with you.
If you have, proceed to uninstall electrum. Search for the program files folder to find out if it is still there. If yes, then delete the file. Next go to your_computer_name > AppData > Roaming
Search for electrum folder then delete it.
Start afresh by doing new installation. Use your 12-word seed to recover back your coins.

I was able to find that config file , removed it and now I now can run Electrum fine . but why I had that problem exactly ? should I delete the Config each time ? It dosen't make sense at all to me .
The developer should be the best person to answer your question. But anyway, your case seems to be isolated. I never have any problem with electrum not being able to open or crash and it works great thus far.
Alright , I will try to contact the developer or post on the Github page they have . and the wallet seem to work fine anyway .... It just sometimes don't run (show for seconds on TaskManager then get closed) ones I delete the config file as the guy above said , It come back to work fine , so weird
thanks for your answer mate
