Error when try to run quickstart

I have an error when run tutor local quickstart with Tutor v.11.2.6. The error occurs in the part of Database creation and migrations when it tries to initialise the lms service. This is the first time I found this error and didn’t know how to solve it. I tried to remove the data folder but it didn’t work.

Something is causing the lms.env.json file to have an invalid format:

yaml.parser.ParserError: while parsing a flow mapping
  in "/openedx/config/lms.env.json", line 1, column 1
expected ',' or '}', but got '<scalar>'
  in "/openedx/config/lms.env.json", line 30, column 4

It’s almost certainly an invalid plugin. What is the output of tutor plugins list? What’s at line 30 of $(tutor config printroot)/env/apps/openedx/config/lms.env.json?

For plugins list

tutor plugins list

license==11.0.0 (disabled)
minio==11.0.0 (disabled)

xqueue==11.0.1 (disabled)

and at line 30 of lms.env.json

What about line 29? This line includes your CONTACT_EMAIL. Make sure it does not contain any weird character.

I got it! it’s my mistake. I didn’t notice that the contact email is set to “”. Thank you for a guide.
