box drive not syncing to 1 out of 3 computers

Hi, the box drive stopped syncing a while ago to my macbook. Everything syncs fine to the other two computers (a Windows 10 and a mac desktop). On the web client everything is set to sync (otherwise I would not see it btw the PC and the mac desktop).

The software is installed (v2.37) and it claims "no active transfers" - in the box folder most content has a green checkmark, but some folders/files have a yellow circular arrow, but it seems nothing has updated since Nov.28 2023 (I guess i haven't worked from home on this project since then).

Dunno what else to try?
