When I place a block it sometimes disappears from my inventory too

The day of the new update happy ghast everything was fine the next day blocks started to disappear when I placed them, I also had a lack of texture when destroying a block, only after destruction there was a texture The block fell to the ground for 8 seconds. I have 30 to 40 FPS overall so it's not the phone's fault because before the happy ghast update nothing was lagging or disappearing. I don't feel like playing a game like that with such lags, I just lost interest because of the lags
