Power BI Desktop WebView2 crash

I've been trying to do the right thing and leave WebView2 on for the last few months, multiple machines.

I've rolled most of my machines back to July as the August build was just a total dud (many other issues). August QFE2 is now out (dated 26 August), which does seem to fix most of the other issues. But it's WebView2 seems an absolute mess again, unusable.  I've turned it off and hope to be able to get some actual work done.

Microsoft do not seem to appreciate that the thousands (millions?) of authors using Power BI Desktop generate the content that convinces execs and IT managers to buy Power BI licenses. The quality of Microsoft's work on Power BI Desktop has been really poor lately, basic testing seems to be skipped and major issues like this fester on for months. It frustrates me intensely as I spend most of my days working in this product.
