where is SVI for 204 (interface vlan 204) ? check if it is UP UP state. if you don't have SVI 204, then you must have L3 port with ip address on switch Or a router doing ROAS (router on a stick)
if PCs are not directly connected to switch with SVI 204, then check trunks if they allow to pass vlan 204.
finally, there must be at least 1 access vlan in 204 for interface vlan 204 to stay up up.

Sorry for the late reply but I was on vacation all my SVI vlans are created on my core switch and they are distributed as layer 2 two my other switches on my access switches I have a management vlan which is 8 but all my vlan on the other switches are layer 2 and my issue is that when I connect my laptop to vlan 204 i'm able to ping the gateway of that vlan but i'm not able to ping switch 3 or switch 4 but if I put my laptop on the same switch but on a different vlan i'm able to ping swtich 2 and 3 and all my vlan are on all the switches and i'm able to ping from swich 2 and 3 from a different vlan except from vlan 204
if you have extended VLAN to other switches, there is no reason 1 work 1 will not, until any other ACL or another information we do not know as part of the config.
As i have requested earlier, we need to look at your switch config, so please post-core and switch 2 and 3 configs (removing any sensitive information)
