My Monero GUI wallet cannot send! I've tried repeatedly on different computers, tried restoring wallet, it crashes or gives the message "Can't create transaction: Unexpected error: Call method failed." What is wrong?? Using latest GUI wallet (monero-gui-install-win-x64-v0.17.1.9.exe) connected to Trezor Model T on Windows 10. Is all my XMR frozen forever???
There's a bug present in the Trezor code that causes the GUI to crash occasionally whilst trying to send. This will be fixed in the upcoming release. See:
In the meantime, please try sending a smaller amount of the balance.
