Queries Metadata M Engine Error

[StevenF19]

Hello,

After the recent Power BI desktop update, I've been prompted to upgrade one of my reports to the enhanced metadata format. When trying to do so, I'm getting the below error. Wasn't able to find anything online about any Queries Metadata errors and I can't find anywhere to look at this in the advanced editor. Any help would be much appreciated as I can't make changes to my report because of this.

Tried the above suggestion and it didn't work. Ended up reverting my Power BI version a couple months ago to fix it but now I needed to update Power BI and I'm running into the same issue. Hoping that someone has an answer to this.

Hoping someone can help resolve this as this latest update has broken several of my reports and I am no longer able to make changes to their data models.
