This issue has been occurring for months, I recently replaced my laptop and the issue occurs before and after the replacement. Happened after a fresh install as well.
Here is the issue when file explorer is maximised. You can see through the tabs (note the Phone Link window open in the background) and click through them too (on the part where there is supposed to be a bar painted) to get to Phone Link.

This is what it looks like when not maximised.
