I am sad to hear that you need to rely on SMB 1 (NAS). Usually network neighbourhood will not show devices in 24H2 for security reasons also SMB 1 is Normally off by default.
If you don't care for security check for the following
Check if SMB 1 in installed and enabled
Click on systray > networking °in settings app change the network from public to private.
Open legacy control panel> network > network neighbourhood and enable discovery
Disable SMB signing as per this article.
Mind that all of this means man in the middle attacks are then possible, your password can be easily stolen and compromise (encrypt, modify or delete ) your data. This is all a thing that happens in reality and hackers, depending their targets, don't care whether it's business or home.
The best thing is try updating Firmware and hope these devices like TV and NAS can Support setting up SMB 2 or better 3 and SMB signing. And abstain from network neighbourhood discovery.
