Depending on configuration of "3rd party" devices you may be creating loop(s) in your LAN. One potential loop is between CRS328 and openSense router, another potential loop is between CRS328, CRS305 and unRAID. Any of these loops will break connectivity for one of involved VLANs.
There's xSTP which detects loops and if one is detected, it blocks one of involved ports. Only MSTP considers VLANs in the loop detection algorithm, other dialects (RSTP and legacy STP) work on physical layer.
If I was trying to do your job, I'd reconfigure existing link to trunk (so it'd carry both VLANs). If the other link is desired for high performance/availability reasons, nake tgem a bond and carry all VLANs over bond. In case of unRAID this would (in principle) mean establishing a MLAG environment between CRS328 and CRS305, but I'm not sure if this would actally help in any way (depends on other devices, connected to CRS305).
