Hello Affinity,
i found an issue. When i try to open multiple images in same time (f.e. 6 images), the designer .82 freeze and there is info about "opening 6 files", but nothing happens. CPU load is above 90%. I tried to let it work for about 1 minute, but designer opened nothing. Those files are .jpg (saved from Ps for web), about 2Mpx resolution, hundreds Kb each, so relatively small images (newsletter designs in my case). I attached screenshot captured in progress of opening.
