Try adding exclusions in Windows Defender for the TB Profiles folder:

- in Windows, click Start and type: virus
- click Virus & threat protection System settings > Virus & threat protection settings > Manage settings
- scroll down to Exclusions > click 'Add an exclusion' > Folder
- navigate to and select the Thunderbird Profiles folder (all profiles - usually at C:\Users\<username>\AppData\Roaming\Thunderbird\Profiles) > click 'Select Folder'
   - to locate the Profiles folder:
     - TB menu > Help > Troubleshooting Information 
     - Application Basics section > scroll down to 'Profile folder > click the 'Open Folder' button
     - navigate up two levels 
IMPORTANT: also go to TB menu > Settings > Privacy & Security > Security > Antivirus and enable 'Allow antivirus clients to quarantine individual incoming messages'.
