The dates of recent kernel changes on my system have been
5.4.0-91 Nov 30th 2021
5.4.0-92 Jan 5th 2022
5.4.0-94 Jan 11th 2022
I do not understand how the option to boot 5.4.0-91 which you had available on Jan 5th has disappeared.
Did you run any apt remove commands or the Lite Tweaks Kernel Remover at all in the meantime ?
Provided your timeshift image was made on a good working system your plan sounds ok. That would be while you were reverted to 5.4.0-91 using GRUB, though your first post of Jan 16 talks about making a back up of 5.4.0-92 (which is partly why I am confused). Obviously you will need to keep the timeshift archive safe through any changes you make while reverting to the older source.
If it works reliably, GRUB can be set to always boots the working kernel. But that is not a great idea so you will need to know what the error actually is so that you can search for the issue and check for bug reports/fixes in subsequent kernels.
I am struggling to come up with a kernel issue scenario in which it can work intermittently so make sure the system boots reliably on whatever solution you come to.
