Cannot set remote breakpoints in Visual Studio Community 2022 (Version 17.9.3)

Start with debugpy/_vendored/pydevd/pydevd_file_utils.py, especially set_ide_os(os), and compare the attached adapter, pydevd, and server logs with the reported path translation steps. Reproduce the Windows-to-Ubuntu remote attach using the listed environments and inspect the slash conversion around the translated path. Done means both pre-set and post-connection breakpoints resolve to /home/shamada/debug/b.py instead of reporting that the file does not exist.

Symptoms

Remote debugging using VS2022+debugpy does not work properly.
The remote connection is successful, but Breakpoint cannot be set.

Environmental Data

Client environment

• Windows-10
• Visual Studio Community 2022 (ver 17.9.3)
• debugpy 1.8.0
• workdir: \10.123.36.238\shamada\debug\

Server environment

• Ubuntu-22.0.4
• Python 3.11.5
• debugpy 1.8.0
• workdir: /home/shamada/debug/

Execution steps and results

Execution steps

[server side]

export DEBUGPY_LOG_DIR="/home/shamada/debug"
export DEBUG_PYDEVD_PATHS_TRANSLATION=1
export PATHS_FROM_ECLIPSE_TO_PYTHON='[["\\\\10.123.36.238\\shamada\\", "/home/shamada/"]]'
conda activate py311a
python -Xfrozen_modules=off -m debugpy --wait-for-client --listen 0.0.0.0:5678 b.py

[cliennt side]
execute "attach to process"
execute "python remote (debugpy)"

Results

Pre-set breakpoints will be disabled.
Breakpoints set after connection are also disabled.
Both breakpoints are given the error message "Breakpoint in file that does not exist."

Investigation

debugpy.pydevd.log contains logs like the following.

0.00s - Request for breakpoint in: \\10.123.36.238\shamada\debug\b.py line: 3
0.00s - pydev debugger: replacing to server: \\10.123.36.238\shamada\debug\b.py
0.00s - pydev debugger: sent to server: /home/shamada/debug\b.py - matched prefix: \\10.123.36.238\shamada\
0.00s - Breakpoint (after path translation) in: /home/shamada/debug\b.py line: 3
0.00s - os.path.exists('/home/shamada/debug\\b.py') returned False.

It seems that the cause is that slashes and backslashes are not converted properly in path mapping.

Please see the attached file for all logs.
debugpy.adapter-4104855.log
debugpy.pydevd.4104847.log
debugpy.server-4104847.log

Additional attempts

Referring to the previous issue below, I modified the system file below on both the client and server.
Cannot set remote breakpoints in Visual Studio Community 2019 (Version 16.6.1)

File: debugpy/_vendored/pydevd/pydevd_file_utils.py
Location: in set_ide_os(os) function

Add the following.
os = 'WINDOWS'

The symptoms did not change.
