Fatal Python error: _enter_buffered_busy: could not acquire lock for

[m-deg]

I am suddenly not able debug a python program. I used to be able to do this. But when I try to start debugger thru nvim-dap, it says "Debug adapter didn't respond, either the adapter is slow or there is a problem with your adapter configuration."

dap.log prints following error:

[ ERROR ] 2024-06-16T22:39:04Z-0700 ] .../deg/.local/share/nvim/lazy/nvim-dap/lua/dap/session.lua:1455 ] "stderr" { args = { "-m", "debugpy.adapter" }, command = "/home/root/.install/.pythonvenv/spacy/bin/python3.11", enrich_config = <function 1>, options = { source_filetype = "python" }, type = "executable" } "Fatal Python error: _enter_buffered_busy: could not acquire lock for <_io.BufferedReader name='<stdin>'> at inter preter shutdown, possibly due to daemon threads\nPython runtime state: finalizing (tstate=0x000055bc6dfa89f8)\n\nCurrent t hread 0x00007f373c081740 (most recent call first):\n <no Python frame>\n" [ INFO ] 2024-06-16T22:39:04Z-0700 ] .../deg/.local/share/nvim/lazy/nvim-dap/lua/dap/session.lua:1428 ] "Process closed" 3 55193

my debugpy version seems to be fine as well:

$ /home/root/.install/.pythonvenv/spacy/bin/python3.11 -m debugpy --version 0.00s - Debugger warning: It seems that frozen modules are being used, which may 0.00s - make the debugger miss breakpoints. Please pass -Xfrozen_modules=off 0.00s - to python to disable frozen modules. 0.00s - Note: Debugging will proceed. Set PYDEVD_DISABLE_FILE_VALIDATION=1 to disable this validation. 1.8.1

Any ideas?
