MySQL connection error without native SQL query

I am trying to connect (get data) to one of the MySQL databases and receive an error: "An entry with the same key already exists".

30d10f9ec5fd4424214b39f9c643f61b
I can't even see what tables are available.

When I use native SQL query or try to connect to other DB then problem doesn't occur.

Hi, @technolo_bi ;

Clear permissions in data source settings and try the latest version of Power BI Desktop.

It seems that the error is essentially a duplicate column name error,

Hi @v-yalanwu-msft,

I can't even select a table, so where should I look for duplicate column?
