Thank you Seb Once I realised that mine was the only user account on my home desktop PC with this problem, I tried deleting all hidden config files that included the words "Nautilus" or "Gnome". This did not help so I created another sudoer and removed my home folder. I then recreated my home folder using cp /etc/skel. As explained in my earlier post, this action has removed the problem. I now feel that this issue is unlikely to be replicable by others.
However in case it useful I followed your suggestion and put "journalctl -b 0" into a terminal and below is the result. I have only copies part of the output. I'm afraid I do not understand any of this myself. -- Logs begin at Wed 2020-04-29 19:21:25 BST, end at Mon 2020-05-18 16:42:40 BS> May 17 13:04:20 susan kernel: microcode: microcode updated early to revision 0x> May 17 13:04:20 susan kernel: Linux version 5.4.0-29-generic (buildd@lgw01-amd6> May 17 13:04:20 susan kernel: Command line: BOOT_IMAGE=/boot/vmlinuz-5.4.0-29-g> May 17 13:04:20 susan kernel: KERNEL supported cpus: May 17 13:04:20 susan kernel: Intel GenuineIntel May 17 13:04:20 susan kernel: AMD AuthenticAMD May 17 13:04:20 susan kernel: Hygon HygonGenuine May 17 13:04:20 susan kernel: Centaur CentaurHauls May 17 13:04:20 susan kernel: zhaoxin Shanghai May 17 13:04:20 susan kernel: x86/fpu: Supporting XSAVE feature 0x001: 'x87 flo> May 17 13:04:20 susan kernel: x86/fpu: Supporting XSAVE feature 0x002: 'SSE reg> May 17 13:04:20 susan kernel: x86/fpu: Supporting XSAVE feature 0x004: 'AVX reg> May 17 13:04:20 susan kernel: x86/fpu: xstate_offset[2]: 576, xstate_sizes[2]:> May 17 13:04:20 susan kernel: x86/fpu: Enabled xstate features 0x7, context siz> May 17 13:04:20 susan kernel: BIOS-provided physical RAM map: May 17 13:04:20 susan kernel: BIOS-e820: [mem 0x0000000000000000-0x000000000005> May 17 13:04:20 susan kernel: BIOS-e820: [mem 0x0000000000058000-0x000000000005> May 17 13:04:20 susan kernel: BIOS-e820: [mem 0x0000000000059000-0x000000000009> May 17 13:04:20 susan kernel: BIOS-e820: [mem 0x000000000009e000-0x000000000009> May 17 13:04:20 susan kernel: BIOS-e820: [mem 0x0000000000100000-0x000000008b85> May 17 13:04:20 susan kernel: BIOS-e820: [mem 0x000000008b852000-0x000000008b85> May 17 13:04:20 susan kernel: BIOS-e820: [mem 0x000000008b859000-0x000000008c30> lines 1-23...skipping... -- Logs begin at Wed 2020-04-29 19:21:25 BST, end at Mon 2020-05-18 16:42:40 BST. -- May 17 13:04:20 susan kernel: microcode: microcode updated early to revision 0x27, date = 2019-02-26 May 17 13:04:20 susan kernel: Linux version 5.4.0-29-generic (buildd@lgw01-amd64-035) (gcc version 9.3.0 (Ubuntu 9.3.0-10ubuntu2)) #33-Ubuntu SMP Wed Apr 29 14:32:27 UTC 2020 (Ubuntu 5.4.0-29.33-generic 5.4.30) May 17 13:04:20 susan kernel: Command line: BOOT_IMAGE=/boot/vmlinuz-5.4.0-29-generic root=UUID=c977975b-e6da-444a-b063-5200452dc91f ro quiet splash vt.handoff=7 May 17 13:04:20 susan kernel: KERNEL supported cpus: May 17 13:04:20 susan kernel: Intel GenuineIntel May 17 13:04:20 susan kernel: AMD AuthenticAMD May 17 13:04:20 susan kernel: Hygon HygonGenuine May 17 13:04:20 susan kernel: Centaur CentaurHauls May 17 13:04:20 susan kernel: zhaoxin Shanghai May 17 13:04:20 susan kernel: x86/fpu: Supporting XSAVE feature 0x001: 'x87 floating point registers' May 17 13:04:20 susan kernel: x86/fpu: Supporting XSAVE feature 0x002: 'SSE registers' May 17 13:04:20 susan kernel: x86/fpu: Supporting XSAVE feature 0x004: 'AVX registers' May 17 13:04:20 susan kernel: x86/fpu: xstate_offset[2]: 576, xstate_sizes[2]: 256 May 17 13:04:20 susan kernel: x86/fpu: Enabled xstate features 0x7, context size is 832 bytes, using 'standard' format.

But they stop working: (1) no launch; (2) no right click context to make launchable; and (3) no app icon. They can even remain in ~/Desktop but disappear from the desktop view. A logout kills them. Creating another new launcher is successful and peculiarly triggers the temporary reactivation of all the others. But euphoria soon dies as they all revert to inertia later. My work around at present is to install PCManFM 1.3.1. Navigating to ~/Desktop on PCManFM, my Nautilus created launchers are all visible, launchable and have the usual colourful app icon features. But they remain inert in Nautilus.
