The blocks area did not load properly. Changes to the blocks for screen 6282823334756352_Screen1 will not be saved

Yesterday, I was able to load and make my app to work.
Today while opening my project I got this error "The blocks area did not load properly. Changes to the blocks for screen 6282823334756352_Screen1 will not be saved.".
Also, many blocks are missing and everything is messed up.
Kindly help me with this as I am making this for Appathon 2022.
Also I cannot share the .aia file because this is meant for Appathon...

Send it to me via PM, or you can send it to @dora_paz.
