Sharing folders under Windows 11 Pro over a local Wifi network

Hello, I cannot share 1 folder between 2 PCs running Windows 11 Pro.
1) The folder is in share mode with Everyone in Read/Write
2) I share proximity with everyone
3) I am on a shared private network with automatic network search and file sharing enabled
4) I disabled the public network
5) My wifi is on a private network
6) I disabled the firewall in private network (and network with domain)
 
The 2 PCs are configured in the same way a priori. Only one of the two has file shares
 
I can see the other PC in the file explorer network but cannot access shared folders. I get an error message telling me that I cannot access the computer.
