I cannot open my last recent project at the opening of Premiere Pro Beta 14.9.0 build 9

Ok, in Premiere Pro Beta 14.9.0 build 9, I have set Premiere Pro to open directly on the most recent project. In my project panel, for my last project tab I select "close project". So I am now with the media explorer. Then I close Premiere Pro Beta and re-open it. I am also with my media explorer in the project panel.

If I do file/open recent project and select the name of my last project (called "beta2"), nothing happens (my last project does not load in the project panel).

Then if I open another recent project (called "sanstitre9"), Premiere Pro can now open this other project. Then I close Premiere and when I reopen it, the name of the project has changed in the project panel and I am now with the project I could not open last time (ie "beta2").

If I close again Premiere Pro and reopen it I am now with the other project at the opening ("sanstitre9"), etc... (at the opening : "beta2" ->"sanstitre9"->"beta2"->"sanstitre9", .......) !

Is it a bug ?
