I've been seeing issues with Cmd-H ever since upgrading to Ventura, but unlike the Save As… dialog cursor bug, I haven't seen this one mentioned elsewhere. AE often fails to hide when I use Cmd-H. The UI focus shifts to the Finder, but the AE window remains visible. If I minimize AE, undocked panels remain visible and cause issues. Using the menu command After Effects > Hide After Effects seems to work more consistently than the keyboard shortcut, though that may be coincidence. The problem as a whole is intermittent, not constant, so it's hard to test and provide specific detailed descriptions.
