can not open the app on macOS Big Sur 11.0.1

[relaxssl]

Hello,

I met an issue, after upgraded my macOS to macOS Big Sur 11.0.1, When I try to open Electrum, it is not response, and then I uninstalled it and try again, the issue keeps the same. Any other users meet the same problem?

Need help.

Thanks!

Someone reported a same issue yesterday. Visit the link below.
New to This: Issues with Electrum

Edit:
There are many people having problem with the new version of MacOS.
I just found following threads on reddit.

Electrum still doesn't work on Mac OS Big Sur
Electrum Wallet not working on BigSur
Apple Big Sur update & Electrum

Seems that it's a known issue.
If you have your seed phrase, there is nothing to worry about. You can access your fund using Electrum on windows, android, linux or wait for developers to fix the issue.

Can you try to start electrum via the command line and report back with the error occurring?
