After installing the 2021 october update, there are some strange stuff happening to the measure tools in pbi desktop:
When opening a pbix file, I'm not able to edit an existing measure. When clicking on it, the measure tools / dax bar doesn't show up. I need to create a new measure in order to "activate" the measure tools and then modify the existing measure.
The DAX editor / bar is now really, really slow, it evens makes my typing to not be computed by it. Also, when using <tab> to accept an autofill suggestion for a table/measure, it gets stuck in it.
The functions autofill is now poorer for some commonly used functions as the IF function. If I type IF and then hit <tab>, it will autofill the less used function IF.EAGER which can get really annoying.
