Dear Anjiv,
Although I dont know whether interaction exist or not, You have fİve options. Each may be use. First four may be used with SPSS.
Fisrtly,use another homogenity of variance test such as hartley Fmax to see results also true. In some analysis small variance differences may be result a significant levene result. Levene uses difference scores in each group and perform a ANOVA, So Levene results may be significant If groups size drastically differ or ıf some groups in your data extreme scores. According to Howell (2013, page 234) the results of variance analysismore likely to be valid when the ratio of largest variance to smallest variance was four or below among the groups.
If you want to be conservative,
Secondly, conduct separate one ANOVA, and use Welch F test, and post hoc Games-Howell. report homogenity of variance violated so I used Welch F test and games-howell. In spss equality of means options in One way anova click for welch F test.)
Thirdly, continue your analysis and use post hoc Games-Howell. and report homogenity of variance violated so I used games-howell
Fourth, perform a bootsrap analysis, ıt is no requirement for assumptions.
Fifth, you can also perform a Beyesian ANOVA.
Last note: ANOVA robust the violation of normality assumption. Dont worry about it. Your skewness score also not problematic.
