I do have Qt 6.0.2 installed on this pc and I’ve heard Plex was created with Qt GUI. Although this has probably nothing to do with it I thought I’d mention it.
Yeah, I did what you recommended but it did not work for me. Meanwhile I had to re-install my Windows since I changed my SSDs and now it works. Thank you for your reply.
I had the same problem and it turns out the Plex Window was “off screen”. Alt-Tab brought up the Restore/Move menu. I selected move, and then used the cursors to move it back “on screen”. From there I maximized the window and all was fine.
I have version 1.35.1 and am experiencing the same issue. I recently went as far as to re-image my computer from a recent image I took before the issue started and it was working again for 3 days or so, but now the white screen is back. I can use the web player, but not the locally installed player. I have deleted everything in C:\Users<user>\AppData\Local\Plex folder (I backed it up first) and re-installed the latest version a few times. I even tried going back to an older version from Sept and one in June, the issue persists.
