Thanks
I don't agree with Your conclusion.
RSTP uses untagged frames and since You mentioned RSTP blocks one of the links, it means You have a L2 loop for untagged frames.
Until You remove this loop, don't disable RSTP.
I have a guess about origin of this loop - most likely, You used the "stub bridge-domain+SVI" style of configuring L3 links, and this style allows simultaneous usage of STP and L3 on the same physical port. Please reconfigure the trunks to become router-style tagged links and then You can safely disable RSTP.
HTH
Thx
