Hi @MartySR
I find a similar thread 'OneDrive Ransomware Protection kills Cryptomator - please support!'. Microsoft won't delete your cryptomator folder. For more, please refer to **quantum_libet'**s sharing in the link above.
Besides, you cannot turn the warnings off. Please vote up the thread in "Cryptomator .c9r files falsely marked as ransomware" in Microsoft Feedback forum, your feedback helps Microsoft know which features are most important to you. Thanks for your understanding.
