First bug:
1. Open a .PSDC file
2. Save A Copy (save to creative cloud)
3. Remove Copy in the file name
4. Click "On the computer" button
5. Change the format to WebP
6. Sometimes (mostly initial attempt) it won't let you save it.
Second bug:
1. Open a Quebec Flag Icon.PSDC file (only that file has this particular issue)
2. Save A Copy (save to creative cloud)
3. Remove Copy in the file name
4. Click "On the computer" button
5. Change the format (WebP is not on the list of choices... why?)
