Dynamo crashes - code block problem

Hello all, Some times Dynamo crashes but I save the script. The problem is that when I open again the script I cannot write in the code block nodes (image below). So I need to start the script from scratch… do you have any idea ? I use Revit 2021 and Dynamo 2.6.1.8786 Code block problem|690x397 Thank you in advance!
