 ### Fixed
 - Fix that active segment and node id were not shown in status bar when being in a non-hybrid annotation. [#5638](https://github.com/scalableminds/webknossos/pull/5638)
+- Fix that "Compute Mesh File" button was enabled in scenarios where it should not be supported (e.g., when no segmentation layer exists). [#5648](https://github.com/scalableminds/webknossos/pull/5648)
 - Fixed a bug where an authentication error was shown when viewing the meshes tab while not logged in. [#5647](https://github.com/scalableminds/webknossos/pull/5647)
 
 ### Removed
