I have similar issues. I have used Cakewalk/Sonar for decades and the latest 2 October 2025 release is even worse. I have a Dell tower with 32G ram running an Intel i7 13 gen cpu. I have transfered projects to Ableton Live 11, exact tracks and effects, and absolutely no issues running in Ableton. I love the work flow of Sonar but until they concur issues sorry to say I am moving to Ableton.
