Just downloaded pr8 for test
1. Open "Sample Projects\Cards flipping.pxc", a orange error message window pops, click on other field, return normal.
2.Create an export node, PNG/GIF export works, animated WEBP export will make the main program crash, and I'm not sure if this feature ever worked, just tried to test it out of curiousty today (although I didn't use WEBP personally).
