What could this be??? Mold?? Larvae? Any ideas? I’m stumped.

Expecting baby 2 next month and just noticed these weird spots on our ceiling. The first picture shows where our ceiling tape is cracking (we had a water leak in 2021, painter spackled over it since it was minor and repainted). The arrows point to a few of the spots. They’re tiny. There are 3 to 4 in this area and then 4 to 5 in another area near cracking tape.

The closeup looks SO weird!! Anybody with experience know what this could be??
