Multiple solutions opened and the window focus keeps switching back to the first solution

I tried googling this issue, but nobody else seems to be experiencing it.

I usually open multiple solutions and work on them by switching between windows. The problem is that focus automatically jumps to the first solution whenever I navigate to a different file or view (or do almost anything). I then have to switch back to the solution I was working on every time I want to edit something — or just keep a single solution open at a time.

I'm running Rider 2026.1.3 on macOS 26.5. The previous version (I think it was a release from about four months ago) worked fine, but this strange behaviour started right after the recent update.

I installed a fresh new Rider EAP and it seems mostly fine but the focus still changes to the first solution when I double click on a file during PR reviews.
