Critical Error Trying to Create Newsletter

[User]

My newsletter creation function is suddenly not working. Attempting to create a newsletter results in this error:

How can I fix this? My host suggested uninstalling and reinstalling but was not sure if I would lose subscribers by doing so.

Yes, there is a problem with version 8.9.6. Please update to version 8.9.7; it should be fixed. Let me know, thanks.
