Plugin out of nowhere stopped working inside Gutenberg editor!

Hello! I’m having the following problem! Plugin suddenly stopped working inside Gutenberg editor. Before, I typed a PHP code in any part of the Editor and it was automatically recognized as a PHP code. Now it doesn’t work anymore and where I had the block it appears an error message saying that there was an error in the block, it doesn’t work anymore! Can someone give me a hand!?
obs.: I already deleted and reinstalled the Plugin and it didn’t work anyway!
