run this command on terminal:
/www/server/panel/pyenv/bin/python -m pip install --force-reinstall "anyio==4.14.2"

then test:
/www/server/panel/pyenv/bin/python -c "import anyio; print('Version:', anyio.version if hasattr(anyio,'version') else 'OK'); print('abc:', hasattr(anyio,'abc')); import anyio.abc; print('IMPORT ABC: OK')"

it should be:
abc: True
IMPORT ABC: OK

finally restart panel:
bt restart

Hello.
Manually execute this command to reinstall anyio, and then restart the panel is it normal? Do not restart in the panel terminal

btpip uninstall anyio==4.15.0 -y
