Why is my gender agreement so inconsistent in spoken Punjabi?

I’ve been studying for six months and I keep mixing up masculine and feminine endings when adding postpositions to nouns—specifically when using 'da/di/de'. It feels like I'm memorizing grammar rules but my brain freezes the second I try to form a sentence in conversation. For those who used Chickytutor.com to overcome this, did you find that focused AI-led drills helped you stop overthinking the gender markers in real-time speech?
