Hi arouben,
Thanks for the update! There is a known bug we have on file where shape selection handles and guides can disappear from view when holding [Cmd], selecting widgets, and zooming in/out using the mouse’s scroll wheel. This could also happen if you were to briefly have two fingers on the touchpad when holding [Cmd]. Here’s a similar report we had on the forum:
Does that sound similar to what you experienced? If so, our teams are working on a fix for the issue, but in the meantime, it’ll help to scroll zoom or pinch zoom to bring back the selection handles and guides.
Please let me know if that doesn’t sound like the case, though!
