It sounds like you managed to delete the remote externally somehow, and now OpenLP thinks that the remote is installed, but it's not.
Let's try clearing the version number so that you can download the web remote again.
Open TextEdit and Paste the following contents into it:
[SettingsImport]Make_Changes=At_Own_RISKfile_date_created=2022-02-09 10:50[api]download version=[settings]version=2
Save the file as
Then go into OpenLP, File menu -> Import -> Settings. Click OK to the warning message, and then select the
file you created. OpenLP will close and you'll need to open it again.
Go back into the settings, and click the "Upgrade" button.
If the remote files are still being deleted, then we need to figure out what's going on with macOS, OpenLP doesn't ever delete those files.
