Send transaction not possible on Trezor / Sys Electrum

Hi - I have updated the latest firmware on Trezor, signed with Trezor One on Sys Electrum, chose native segwit.

I was able to receive SYS but I am unable to sign the transaction to send SYS. It says : key error

Refraining from uploading the screenshot in case it contains sensitive info.

Could use some help in being able to move my coins.

Thanks in advance,

can someone provide an update on this ?

Can you try again now?
