yes i verify the software, and i reinstalled everything now and did all setups again , will there be a problem if i start using it again?
Simply uninstalling and reinstalling Electrum is not enough. You do not yet know for sure how your wallet was compromised. It could have been your Electrum version, it could be malware on your computer, it could be how you stored your seed phrase, it could be something else entirely. If you cannot work out how your wallet was compromised, then at a minimum you'll need to format your computer and reinstall your OS from scratch to be sure you do not still have malware on your device.
also when i use older electrum version it open without needing kleopatra to be open, but 4.4.2 version needs that other app so it will work, it's confusing/
Why do you have two versions of Electrum installed?
Unless you have made a typo, then version 4.4.2 is malicious. The latest real version is 4.2.2.
Electrum does not need any other apps open to run. If your Electrum is opening other things in the background, then chances are it is malicious.
