I have recently migrated to new PC, first tryied with copied AppData folders for Adobe programs, then deleted them to get fresh ones but nothing helps. Whenever i select multiple layers or artboards and use "export as" option, some of them will load previews, some wont, after some time watching them "load" with spinning circles, they become yellow marks with "unknown error". Tryied resetting preferences from within photoshop, tryied starting with ctrl+alt+shift to get fresh preferences, tryied turning off, restarting and turning on the gpu accelerration... Nothing helps. Please advice what to do. Im on 21.1.2 version (up to date today) update: Seems the problem is only with the previews in "export as" window. When i click export, all files seems to be exporting normaly. update2: noticed even more issues. The "export as" window completly missmatches stuff like dimensions. Also while im using "export as" on multiple artboards, picking one in the window and changing png to "small size 8bit" works completly awkward, whenever its checked, it gives bigger size in the preview and if unchecked its small. Also while checked it changes format from i.e. 1080x1080 to 300x250 (propably due to some bug it takes these from different artboard to be exported... Thats a complete mess... I even went ahead, uninstalled entire creative cloud, removed all AppData "Adobe" folders and did a clean installation to eliminate some old conflicting appdata files. It still happens. I might also add that im on a 2 days old fresh windows 10 pro installation. update3: reverting to 20.0.9 didnt change anything. Same issue persists. update4: better representation of the missmatch problem that acompanies the preview loading probleem (note the layer names on the right side and on the "export as" window): edit: shortcut to reported Ryzen cases of other people with same issue: https://community.adobe.com/t5/photoshop/export-as-issue-photoshop/td-p/10936950?page=1 https://community.adobe.com/t5/photoshop/quot-export-as-quot-thumbnails-preview-problem/td-p/10973602?page=1 https://community.adobe.com/t5/photoshop/properly-support-for-amd-apu-ryzen-vega/td-p/10791355?page=1 https://community.amd.com/message/2973199?commentID=2973199#comment-2973199
