I don't use Telegram and most users here prefer it in public so it can be used for reference like solving related issues.

Have you checked your logs if there are error-related entries?

Or if you want fast results, share your transaction here so we can check what's wrong with it.
But that includes a privacy issue, share only if you don't mind sharing info like sender, recipient and amounts.
You can get the unsigned RAW transaction from (after clicking "Pay..."): "Preview->Share->Copy to clipboard".

I only got a glimpse of a small portion on the amount from your screenshot but it looks like you're sending A LOT of bitcoins.
Perhaps there's "something" in the inputs that you're trying to spend that causing errors that aren't in the list of common errors in Electrum.
