A SHIFT+ SPACE keyboard shortcut for the rotate canvas tool was introduced in a minor version update of Ai 25 (sometime after 25.2.1). This keyboard shortcut is very disruptive when trying to make selections while panning around the artboard. For example, you used to be able to continually hold down the SHIFT and SPACE keys to pan around the artboard while quickly dragging the cursor around points or objects to add them to your selection. With the new rotate canvas shortcut, you have to carefully press SHIFT, make your first selection, release SHIFT, press SPACE to to pan, release, press SHIFT again and add to your selection, release, and so on. This is not a comfortable key combo and it makes it very easy to accidentally release your entire selection. Prior to this update, we've never had a need for a quick toggle shortcut for the rotate canvas tool on desktop. If the tool is needed, it is accessible via the hand tool quickly enough. This issue is present in version 25.4.1 and 26.0.1. Starting with version 25.4.1, Adobe added a Preferences option to disable the trackpad gesture to rotate view. Please either disable this toggle shortcut completely or also add an option to Preferences to disable the SHIFT+ SPACE keyboard shortcut for desktop users.
