Phaser.Time.Timeline Errors on calling destroy

[saintflow47]

Version

• Phaser Version: 3.80.1-3.85.0-beta.1
• Operating system: W10

Description

An issue happens on both versions when trying to destroy a timeline like this, even while it is playing. The error is different for each phaser version though.

Example Test Code

                const follower = this.scene.add.follower(curve, 0, 0, "img", "id/ranks/star");
                follower.setVisible(false)
                follower.startFollow({
                    from: pathProgress - 0.5 < 0 ? 0 : pathProgress - 0.5,
                    to: pathProgress,
                    duration: singleDuration,
                    delay: fullDuration-i*singleDuration*mp
                });
                const bloom = follower.postFX.addGlow(0xffffff,3,2)
                const timeline = this.scene.add.timeline([
                    {
                        at: fullDuration-i*singleDuration*mp,
                        run: () => follower.setVisible(true)
                    },
                    {
                        at: fullDuration-i*singleDuration*mp,
                        tween: {
                            targets: follower,
                            angle: this.getStarAngle(starCount, i)-(360*2),
                            duration: singleDuration,
                        }
                    },
                    {
                        at: fullDuration-i*singleDuration*mp+600,
                        tween: {
                            targets: bloom,
                            innerStrength: 0,
                            outerStrength: 0,
                            duration: 500,
                        }
                    }
                ]).on("complete", () => {
                    if(this?.visible){
                        follower?.destroy();
                        this?.addDivisionStarInFinalPosition(curve, pathProgress, starCount, i);
                    }
                }).play()
if(timeline?.isPlaying())  timeline.destroy();

on 3.85.0-beta.1 the error is as follows: Uncaught ReferenceError: i is not defined at Timeline2.clear (phaser.js:233673:14) at Timeline2.destroy (phaser.js:233752:14)

on 3.80.1 the error is as follows: TypeError: Cannot read properties of null (reading 'events') at Timeline2.destroy (phaser.js:233464:41)

Hi @saintflow47. Could you provide full source code and if possible a link to jsfiddle or codepen so we can investigate further? Thanks.
