Works on PopOS

Thanks Max. Could you try running Sparrow in debug mode? On OSX this is easiest with

open /Applications/Sparrow.app --args -l DEBUG

There will be a lot of logging, but the particular log line I'm looking for is Error loading libsecp256k1 library - particularly the stacktraces and causes beneath it. You may get it when you try to sign a Taproot transaction. Alternatively, keep an eye out for an UnsatisfiedLinkError - my hypothesis is that the libsecp256k1.dylib library is not linking correctly on Monterey and thus failing to load.

The libsecp256k1 libraries for OSX and Linux have been updated in https://github.com/sparrowwallet/drongo/commit/3a061cb73ae318fcbe7ea1dcb0b670e78803d9fa

It is possible to run Sparrow from source (see the project README for instructions) to check if it resolves the issue?

This is now fixed in 1.5.3-beta1

Thank you!
