Electrum often crashes for me too, on my desktop. It happens right after broadcasting a transaction from a hardware wallet, and I've reproduced it with different versions on different (Linux) systems.
I have never seen that on my end, but I use Windows, so it might be a compatibility issue between Electrum and your Linux distros. To make things worse, maybe it also involves some hardware you are using. Have you ever used Electrum on Windows PC and how did that go?
The mobile version of Electrum gets on my nerves because there is often no back button. Not in the app and it doesn't accept the back button on my phone. Trying to go back to the previous screen results in a crash or my phone closing and minimizing the app. The PC variant is an excellent piece of software. The mobile version unfortunately looks and feels like a weekend project by a group of University students.
