Description
When opening a standalone file (that does not have a project root), pylint crashes and no diagnostics are displayed.
Traceback (most recent call last):

FileNotFoundError: [Errno 2] No such file or directory: ''
The failing code is
with Popen(cmd, stdout=PIPE, stderr=PIPE,
cwd=document._workspace.root_path, universal_newlines=True) as process:with document._workspace.root_path being an empty string. The problem is that the Popen cwd argument is always set, regardless of the root_path. To make this work, the value should be set to the directory of the file if no root path exists.
This works for me
if not (cwd := document._workspace.root_path):
cwd = os.path.dirname(__file__)
with Popen(cmd, stdout=PIPE, stderr=PIPE,
cwd=cwd, universal_newlines=True) as process:Pylsp version: 1.7.2
