What happened to Jokić's 3P% since the first half of the season?

During the current and ongoing season (which is the 2024–25 season),

• During his first 39 games (24th October 2024 through 25th January 2025): 80/167 ≈ 47.9%
• During his last 23 games (27th January 2025 through 15th March 2025): 37/116 ≈ 31.9%

• Total (62 games): 117/283 ≈ 41.3%

• His last 5 games have been particularly bad: 6/30 = 20%

What are some possible explanations?

Fatigue? Better defense? Luck/regression to the mean? Others?
