Beast Piglins, Piglins losing texture

Today I was playing on the ruins of the bastion, and the piglin-beast froze in place. I tried to attack him, but no damage was done. Then something invisible killed me. Since I was standing in the corner, I could only be attacked from the front. The chat showed that I was killed by a piglin beast. Earlier on version 1.16.100 I noticed the same problem with piglins. I tried to barter, but they did not pick up the bars. Then they jumped off and moved to another. The ingots were not picked up, and I could not inflict damage on them when they were measured. The problem remains in 1.16.101 .
