Click/drag to select all the keyframes that have a classic tween applied to them. In properties panel, find the SYNC check box and click it. This feature ensures the nested frames inside your Graphic symbol (typing animation) will be in sync with the parent timeline's frames. The problem is with the insert of keyframes after a classic tween is made, the nested animations start on frame 1. ... View more

Have you tried the "[" and "]" keys? They are shortcuts for the Brush tool size which reflects the erasor size. Unfortunately Brush and Erasor sizes are tied together in Animate. Doen't make sense but that's what it is. ... View more

Using those artistic stroke brushes is an accumulative resource issue. The more strokes you create with them, the more Animate uses system resources to cache them - at least that's what it can feel like to me. I have experienced some brushes tend to cripple the fastest CPUs faster than others while some brushes seem to fine overall. The fact is, these are vector strokes that are trying to look like raster brushes and they are simoply complicated objects that require resources from the CPU to draw. The more strokes drawn, the more resources it takes. I'm on an M1 running Ventura and Animate seems to do fine using some brushes sparingly while others will lag from the moment I stop drawing so that they can actually render themselves on the stage. I will even get the beachball to spin after a short while.  I wish Animate handles the rendering of brush strokes better but I also find switching to View > Fast can help. Moho software does this automatically as it is also a vector drawing/animating application but when authoring artwork using the tools, the preview is auto-aliased to avoid the lag caused by a high CPU-demand. I'm sure my technical knowledge of what's happening behind the scenes is slightly off but overall, these brushes you're using are simply demanding too much from the computer to render with each added stroke. If you use the regular Brush tool, it's much more responsive. ... View more

Mac or Win? If Mac, did you update to Ventura recently? I've also experienced crashes recently and it was after updating the OS. If not, refer to Kglad's response. ... View more

I have experienced the same issue regarding warped objects that are the result of using the Asset Warp tool. This issue is not isolated to imported AI assets. I've had Animate-generated vectors become corrupt after they were converted to warped objects and not necessarily from crashing. I've opened up older FLA files (older = weeks) and the animations I created using the Asset Warp tool, while still animating, are empty because the warped objects became corrupt.  It's hard to reproduce as it seems to be random but I suspect it might happen after updating Animate to a new version.  For me, in order to finish the animations I started to be able to deliver a final project, I had to revert to an older saved version and then save it as new and most importantly, I converted the animations that use warped objects to keyframes, then break apart every keyframe (use Edit All Frames feature) until each key contains the warped objects, then break aprt again until either each key is an object drawing or actual vector art.  Essentially, use the asset warp tool to create your animations (after saving your FLA as a different file with new name after art is created) then convert to keyframes and break apart to remove all warped objects. It's the only way I felt confident enough that I was going to be able to finish my project(s) until the tool become more stable.   Sorry but this is the best advise I can give you at the moment., ...
