After SU12 stuck on searching for updates with more than 1025 Items in OneStore Folder

Having the same problem since the SU12 update : MSFS gets stuck on “checking for updates”
I tried :

  • deleting and reinstalling MSFS : no difference
  • limiting the data transfer rate to 40 Mbps : worked once
  • limiting the amount of add-ons in the community map : it’s either hit but mostly miss

PS :
I’m using a self build desktop : 7950X3D, RTX 4090, 64GB DDR5 6000Mhz RAM.
MSFS is installed on a 2TB PCIE SSD and the community add-ons are placed on a 4TB PCIE SSD.
