From the article:

The official X (formerly Twitter) account of Take’s Uzaki-chan Wants to Hang Out! (Uzaki-chan wa Asobitai!) manga stated on Thursday that while the manga was originally planned to have a new chapter this month, the manga is now on hiatus due to the author’s health.

Seems to be lingering effects after mostly recovering quickly:

while they are physically recovered, they do not have the energy to draw.

No word on expected return, but the launch of already announced volumes will proceed as planned.
