Reproducible on desktop system (Lenovo Thinkstation S30) with Ubuntu 20.04.1 LTS with Gnome Shell 3.36.4-1ubuntu1~20.04.2. Steps: log in, physically unplug USB keyboard, plug it again. Keyboard switchers show the switching happens, but layout is not changing actually.
It's also reproducible on Thinkpad X230 with exactly the same package versions. Keyboard is Logitech K780, same for both systems. I've also tried another keyboard (some A4Tech one), the problem is reproducible with it too. It's not reproducible for me with suspend and resume, only in the conditions mentioned above. Here is dmesg output from my system during keyboard plug/unplug. 65536.705683] logitech-hidpp-device 0003:046D:405B.0012: HID++ 4.5 device connected.

Workaround is to restart gnome-shell with Alt-F2, then 'r'.
