I’ve got it!
Kept on trying things and found the issue.
The day before the update, I was trying MSFS2020 Map Replacement v4.2.1.
This tool has a button labeled ’ Back to Bing Map’, which the user must use before closing the app.
I can’t remember, but my guess is that I didn’t use that button.
And apparently some hosts file doesn’t update as it should.
When launching the sim after the update, I didn’t use the tool, so the hosts file had the wrong info.
Now it makes sense that apart from the freezes, I was not getting any Bing graphics.
Tried with the add on active and got no problems at all.
So…
If you’re using
MSFS2020 Map Replacement 4.2.1 (as of today)
Make sure you click on
Back To Bing Map
Before closing the app, specially after any sim update.
Thank you all for your support.
Cheers.
