Looks to me like all channels got the blocking, so just filtering chroma won't fit his.
(Got no direct idea how to tackle this properly in Avisynth, in Vapoursynth I would suggest trying BSRGAN or similar aggressive filters. Or downscale and upscale using RealESRGAN or similar.)
Using something along heavy deblocking (DeblockPP7(qp=32.00)), followed by heavy smdegrain (SMDegrain(tr=4, thSAD=6000, thSADC=3000, interlaced=False)) and some sharpening (CAS(sharpness=0.700)) does this:
