The latest Windows Insider build broke my cmder, and now I don't get the lambda prompt, nor do the shortcuts work (Ctrl+R, Alt+Ctrl+U, etc.). I'd love to help you debug or run other builds.
I tried the latest release (1.13.15.1010) just to confirm, but I was using 1.3.14.982 before, and that's broken as well.
Please let me know how I can help :) I'd love to get this fixed/root-caused.
An image of the current prompt:

@hecerinc Please provide the output of cmder_debug.cmd
Sorry, where do I find this cmd? Or how do I run it?
@hecerinc Open Cmder type cmder_debug. If that does not work it is in [Cmder folder]\vendor\bin\cmder_debug
So I assume you meant cmder_diag 'cause that's the only thing I found, but here it is: https://pastebin.com/znrU0v10
@hecerinc could you also modify the cmder:cmder task and add /d after init.bat but before the " and start a new session and post the output.
@daxgames any update on this? Anything I can do to help?
@hecerinc the paste has expired.
The same issue happens to me on build 20161 (Dev Channel)

@hecerinc I am updating to the Windows 10 2004 now. Just an FYI the last time this happened the issue was Microsoft changed something in the console that broke Clink and it took months to get the clink Dev to fix it. I am not confident this will get fixed quickly or possibly ever.
@hecerinc as I feared. https://github.com/mridgers/clink/issues/543
Oh no
Hey @daxgames, seems like there's some discussion on this in mridgers/clink#543 but it looks like the last commit on mridgers/clink was in 2018 -- is this really a hard dependency for the core functionality in Cmder?
If mrigers/clink is no longer maintained, this issue might break Cmder for everyone once the functionality in Windows build >= 20150 makes it to the stable channel, no?
Clink is the core that makes the Cmder Cmd.exe shell more functional so yes it is a hard dependency. If you use Bash or Powershell then no it's not.
Even if they fix clink 1.x.x it does not work with Cmder and I doubt they will come back and fix Clink 0.4.9 that Cmder uses.
@Stanzilla I know you fixed this last time before @mridgers did. Have you had a look?
Ugh, this might just be the time to give up on clink :/
We could try https://github.com/mridgers/clink/pull/522
@daxgames can you try this? I don't have permissions on the repo https://github.com/cmderdev/clink/pull/1
I will take a look.
I don't have access either. I need to see if I have a machine I can even test this on.
I'll merge your PR @Stanzilla
Thanks! So there are test builds here now https://ci.appveyor.com/project/Stanzilla/clink/builds/34286875/artifacts
@cmderdev/trusted-contributors Sorry for the (multi-year) delay, you should all have the permissions now
@cmderdev/trusted-contributors I compiled the modified clink and tried it on a broken windows insiders build and it did not help
Welp. Was worth I shot. I sadly don't have the time (or skills) to investigate Conhost changes, so any help is welcome.
Hey this might be related to another bug
When using the current Version (1.3.16) the prompt for the powershell seems broken. Instead of a lambda it shows an λ.

This is not the case for powershell core or in earlier versions like 1.3.12. I tried to copy the default profile.ps1 from the 1.3.12 to 1.3.16 but that didn't change anything.
EDIT: I updated the profile.ps1 script and replaced the λ symbol on line 71 with $([char]0x000003BB) and the lambda symbol now shows up again in powershell. This change doesn't break powershell core and could be replacement.
