LLDB does not start, error with tty

I use Qt 6.7.2 llvm-mingw-64 bit for my project. It compiles and runs fine.

When I start the debugger from Qt Creator, it stops immediately.

I think the crucial parts of the log are:

d[GDB] STARTING C:\Qt\Tools\llvm-mingw1706_64\bin\lldb.exe "--tty=\\.\pipe\creator-24836-27687" -i mi
....

d[GDB] UNEXPECTED GDB STDERR: error: unknown option: --tty=\\.\pipe\creator-24836-27687

derror: unknown option: -i

dUse 'lldb.exe --help' for a complete list of options.

d[GDB] GDB PROCESS FINISHED, status 0, exit code 1 (0x1)

 

The debugger itself is correctly installed, I can start it manually:

C:\Qt\Tools\llvm-mingw1706_64\bin>lldb --tty=x
error: unknown option: --tty=x
Use 'lldb.exe --help' for a complete list of options.

Here is the full output of the debugger log:
