I really like e/os/ because of its approach, including choosing which application to use) But when I delete the stock launcher (Bliss launcher), only the back gesture remains working out of the 3 gestures (back, home and the multitasking panel). How can the Bliss Launcher be completely removed to use the launcher I like?
There’s two components to Bliss Launcher, the launcher and the recent apps switcher. You can simply install any other launcher and set it as the default home app, but to change the recent apps switcher you have go through a pretty convoluted process which includes rooting the device.
Normally when you install a launcher, it doesn’t mess with the recent apps switcher, so it’s unusual to have a problem with that unless you went in and disabled Bliss. You can’t actually do that normally, you have to go in under ADB with root granted to disable it.
You didn’t say either way, but it sounds like you disabled Bliss which will give you problems if you don’t replace the app switcher as well.
btw, I have unlocked bootloader and rooted device. I’ve installed Lawnchair (another Launcher). Is there any instructions on how to complete this process so that I can use Lawnchair and completely remove the Bliss launcher?

I’m having the same problem which is how I know about it. You have to use a Magisk module called QuickSwitch to change the “recents provider”.
In my case the launcher I’m using, Lawnchair 14, does not provide a working app switcher (it crashes). That’s a known problem that’s affecting a lot of users. Though it may not be an issue in your case. You’ll have to just try it and see if it works.
At this point I’m still working it out, but in the meantime Bliss is enabled and that’s my recents provider. I may try installing another launcher just to see if I can get a different recents provider working. It would be an ugly hack, but I have a big problem with the Bliss app switcher in the way it’s designed.
I managed to do it successfully 
Manual:

Please reboot for changes to take effect.
fogos:/ $ %
5. Reboot phone and delete Bliss launcher
p.s. There will be small inconvenient thing - when you reboot phone, Lawnchair crashes for the 1st time, you just click close and use it. Lawnchair doesn't fall anymore after 1st crash after reboot.
upd. I installed nightly build from github and I don’t have “p.s. issue” anymore)

Where did you find that documentation? I never saw that. It just said on the FAQ to install QuickSwitch and change the recents provider. I didn’t have any trouble doing that, but the Lawnchair app switcher kept crashing.
I just read their telegram group, their github, and came to the conclusion that this is exactly what needs to be done) And I wrote the instructions here personally based on my experience)
I didn’t have any trouble doing that, but the Lawnchair app switcher kept crashing.
btw, I couldn’t do that, I got an error in QuickSwitch
There’s a fix for that QuickSwitch problem, you need to edit a file to add a statement. I haven’t used the VI editor in ages and when I did have to use it a lot I called it VI hell. It’s a really weird editor the way you have to switch command mode on and off, but hey it was written in ancient times before mouse and X-windows. Anyway, let me see if I can refrence that fix, here it is..
Anyway, I’ll look into that problem later with the switcher crashing. I’m busy right now, but thanks for the references.
