We present high-resolution, high-sensitivity observations of the Class 0protostar RCrA IRS5N as part of the Atacama Large Milimeter/submilimeter Array(ALMA) large program Early Planet Formation in Embedded Disks (eDisk). The 1.3mm continuum emission reveals a flattened continuum structure around IRS5N,consistent with a protostellar disk in the early phases of evolution. Thecontinuum emission appears smooth and shows no substructures. However, abrightness asymmetry is observed along the minor axis of the disk, suggestingthe disk is optically and geometrically thick. We estimate the disk mass to bebetween 0.007 and 0.02 M$_{\odot}$. Furthermore, molecular emission has beendetected from various species, including C$^{18}$O (2$-$1), $^{12}$CO (2$-$1),$^{13}$CO (2$-$1), and H$_2$CO (3$_{0,3}-2_{0,2}$, 3$_{2,1}-2_{2,0}$, and3$_{2,2}-2_{2,1}$). By conducting a position-velocity analysis of the C$^{18}$O(2$-$1) emission, we find that the disk of IRS5N exhibits characteristicsconsistent with Keplerian rotation around a central protostar with a mass ofapproximately 0.3 M$_{\odot}$. Additionally, we observe dust continuum emissionfrom the nearby binary source, IRS5a/b. The emission in $^{12}$CO towardIRS5a/b seems to emanate from IRS5b and flow into IRS5a, suggesting materialtransport between their mutual orbits. The lack of a detected outflow andlarge-scale negatives in \tlvco~observed toward IRS5N suggests that much of theflux from IRS5N is being resolved out. Due to this substantial surroundingenvelope, the central IRS5N protostar is expected to be significantly moremassive in the future.
