Minecraft Bedrock taking too long to load the chunks

Today I went to play Minecraft Bedrock on 1.20 for the first time to test it out, but I noticed that the chunks took a long time to load when I flew. My PC is not very good, but I think it must be a bug because in 1.19 this was not happening. And even if I decrease the Render Distance and the graphics, it keeps happening. I hope this is resolved in the next update.

ps: in 1.19 I played with 16 Render Distance and a 32x texture and it was running normally, and now I have 12 Render Distance and no texture and it's very laggy.
