I upgraded directly from High Sierra to Catalina without any major issues, once I switched to a compatible GPU. Photoshop 2020 (v21.0.1) and the new Lightroom Classic v9.0 (Camera Raw v12) became unstable and jerky with High Sierra and the GeForce 1060 GPU with the last Adobe update. The update from macOS Catalina 10.15.3 to 10.15.4 in VMWare Player 15.5.1 worked fine for me. A couple of automatic reboots were required for the update. Tested on 2 systems with 2 different VM’s.
