Date string cannot be parsed into date/time in Google Sheets

I have an IFTTT integration that writes date strings to a sheet. I'm trying to filter the sheet by days of the week, but in order to do that, I need to be able to convert the date strings into actual dates.

The dates are formatted like this:

August 12, 2019 at 08:40PM

But when I feed it into DATEVALUE, it cannot parse it. I've tried removing the leading 0 before 08:40PM and adding a space between the minute and PM, but no luck.
