@dg2k did you ever post the issue on the developer community forum? As I am seeing the same issue and wondered if you had a link.

No, I didn't post as, in my experience, it is like posting to the ether.
I changed my project back to net7.0 and that solved my issue.

I don’t have a link handy, but somebody else posted this to VS Feedback and it is being actively investigated.

Everything posted to the VS Feedback site is looked at. The VS release notes include links to the items fixed in that release.

This is a bug being tracked at https://developercommunity.visualstudio.com/t/Csproj-Editor-does-not-open-due-to-Andro/10333050 (as well as a few other duplicates).

You can follow the progress in that item. You can vote for it if you're also running into it, and you can add more information if you have details that aren't in the existing issue. Both of these are good ideas to help prioritize in general, though this one appears clear enough that additional information probably isn't necessary.

To my knowledge, this affects only .Net 8 which is in preview and not yet a finished product. It is not yet supported on Q&A.

I encounter this in a solution that contains a MAUI project, but for a C# Class Library project. When I unload and load the project, the properties page appears for a fraction of a second, then the error shows up again.
