Gaia19bxc: very unusual object with a period of 0.0223682 d

From ZTF data. Polar-like orbital saw-tooth light curve (amplitude 1.3 mag) with P=0.0223682 d. Although this may be an intermediate polar with a very high amplitude (see Romanov V48, arXiv:2204.02598), I could not find a longer period. The SDSS color is red (faint in u, bright in z), possible detection in WISE W1. High and low states in ZTF data. Could be an ultrashort period polar.
