Where did you get the above news from? Alcaraz is playing in the Mexican Open that started today and he will be playing his opening game against Mackenzie McDonald within the next 24 hours. So the breakdown seems to be an invention in your imagination.
Let me explain something. Alcaraz was off from playing tennis for near to four months. When he came back and won the Argentina Open it was quite a surprise It is always hard for a returnee to win in his first tournament returning from such a lay-off an example was Djokovic last year - when he failed badly in Dubai and a number of succeeding matches after that.
What is further extremely difficult is to win succeeding tournaments in successive weeks - the record of winning 3 tournaments in successive tournaments over a 3 week period since 2000 is held by Rublev - Berlin, St Petersburg and Vienna in 2020. In recent years even greats like Djokovic and Nada struggled to win 2 successive tournaments over a 2 week period.
Like Zverev who struggled badly after lay-off and seems to be getting back on track after todays win in the first round in Dubai against the very promising Leheka - who last week was a semi-finalist in Doha.
So lets wait and see what happens in Mexico and the upcoming two ATP 1000 Masters tournaments this month. So I think it is too early to invent things about Alcaraz in your normal way.

…this has to be concerning for the long term. He has to work so hard with his physical style one has to wonder if this going to be chronic. That said he always seems to break down in tight games so perhaps there is a mental component.
