Reverb on Project playback when no reverb used anywhere

I now have a reverb on my tracks in Cubase 15 Pro, when no reverb was used anywhere in my project. Any suggestions? I can’t work this way. Thanks for any suggestions.

Is this in all your projects or just one? If the latter, it must be something in that project, if in all projects, maybe you have an audio interface which has a reverb effect included and that is now somehow in the monitoring path.
