I used the Start extension bisect command to determine that this was an issue with the MDX extension. Once I disable the extension, everything works fine.

When did you encounter this issue? After upgrading from 1.7 to 1.8 by any chance?

Hi! Thanks for taking the time to contribute! This has been marked by a maintainer as needing more info. It’s not clear yet whether this is an issue. Here are a couple tips:

• Spend time framing the issue! The more time you put into it, the more we will
• Often, maintainers respond with why for several back and forths; rubber duck debugging might help avoid that
• Folks posting issues sometimes fall for xy problems: asking for a certain solution instead of raising the root problem

Thanks, — bb
