Seems like there are quite a few transactions in the mempool (14k) and this with the blocks full.
You tx has quite a low fee compared to the others (Fee per weight unit 0.25 sat/WU) and it might take you a while to get it confirmed.
The tx will probably get confirmed as this wave clears...
If you have checked the replaceable fee checkbox before sending the tx you can try a replaceable fee.
From the
electrum site:
Increase the transaction fee. This is only possible for “replaceable” transactions. To create this type of transaction, you must have checked “Replaceable” on the send tab before sending the transaction. If you’re not seeing the “Replaceable” option on the send tab go to Tools menu > Preferences > Fees tab and set “Propose Replace-By-Fee” to “Always”. Transactions that are replaceable have the word “Replaceable” in the date column on the history tab. To increase the fee of a replaceable transaction right click on its entry on the history tab and choose “Increase Fee”. Set an appropriate fee and click on “OK”. A window will popup with the unsigned transaction. Click on “Sign” and then “Broadcast”
Depending on how urgent this you can also try the CPFP transaction, the explanation is in the same link.
But I would suggest waiting for another 24hours, especially for 60$.
