Not SR variable - maybe a YSO?
The ASAS-SN light curve is not a typical SR variable light curve
Is it maybe a YSO with increasing magnitude eruptions? Or a symbiotic variable?
Period search including the latest ASAS-SN data gives 197 days period, but the phase plot is not convincing.
Latest ASAS-SN light curve:

Further observations are encouraged.
