The string to be encoded contains characters outside of the Latin1 range.

Hi, 
 
I'm working on a power automate flow. 
 
When I am trying to edit the flow(especially excel actions) in the editor and I get the following message:
 
Sorry, we can't load your flow in the new design tool experience.
You can try reloading the page or switching back to the old design tool experience.
Error message: An error occurred while rendering: Failed to execute 'btoa' on 'Window': The string to be encoded contains characters outside of the Latin1 range.
 
This occurs when editing the flow not running it. 
 
Other actions can be edited normally.
 
Even the Excel actions in the process I have written before cannot be edited.
 
Any help to fix this would be greatly appreciated. 
 
Thanks!
