Script Type: Taproot Policy: tr(BIP39) Passphrase: No Password: No OS: Windows 7 Pro Version: 1.5.2

I created a new Taproot wallet. Every time I try to open it I get

ERROR [JavaFX Application Thread] c.s.s.n.ElectrumServer [null:-1] Failed to start BWT dev.bwt.libbwt.BwtException: Invalid config: unexpected «tr(1 args) while parsing Miniscript» at line 1 column 1278 at [email protected]/dev.bwt.libbwt.daemon.NativeBwtDaemon.start(Native Method) at com.sparrowwallet.sparrow/com.sparrowwallet.sparrow.net.Bwt.start(Unknown Source) at com.sparrowwallet.sparrow/com.sparrowwallet.sparrow.net.Bwt.start(Unknown Source) at com.sparrowwallet.sparrow/com.sparrowwallet.sparrow.net.Bwt$ConnectionService$1.call(Unknown Source) at com.sparrowwallet.sparrow/com.sparrowwallet.sparrow.net.Bwt$ConnectionService$1.call(Unknown Source) at javafx.graphics/javafx.concurrent.Task$TaskCallable.call(Unknown Source) at java.base/java.util.concurrent.FutureTask.run(Unknown Source) at javafx.graphics/javafx.concurrent.Service.lambda$executeTask$6(Unknown Source) at java.base/java.security.AccessController.doPrivileged(Unknown Source) at javafx.graphics/javafx.concurrent.Service.lambda$executeTask$7(Unknown Source) at java.base/java.util.concurrent.ThreadPoolExecutor.runWorker(Unknown Source) at java.base/java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) at java.base/java.lang.Thread.run(Unknown Source)

Indeed, Taproot is not yet supported by BWT: https://github.com/bwt-dev/bwt/issues/91 due to upstream work being required in rust-bitcoin.

The workaround for now is to use an Electrum server.
