Direction keys stopped working on Cmder (ConEmu + clink) from r42

I updated to r42, however on Windows 11 Pro x64 25H2, using Cmder (ConEmu + clink), the arrow keys stopped working: looks like the ANSI sequences like ESC [ A (for up arrow) desync and loose the initial ESC [, showing the error status unknown mapping: A, without any cursor movement (same for all other arrow keys). Going back to r41 gives again navigation keys.

Note:

• Windows Terminal with cmd.exe works correctly
• PowerShell terminal works correctly
• cmd.exe terminal works correctly, even if I start clink
• Looks like a ConEmu configuration issue: I didn't change it for long time though, it's been running all the releases back to r35(?)
