Bind_rows error

[Ade_Forte]

Guys I am all out of ideas here I am trying to bind the rows from four different tables but I keep getting:
Error: Can't combine ..3$started_at <datetime> and ..4$started_at .

I then added a mutate function to the tables
q3_2019 <- mutate(q3_2019, ride_id = as.character(ride_id)
,rideable_type = as.character(rideable_type)
,started_at = as.character(started_at))
q2_2019 <- mutate(q2_2019, ride_id = as.character(ride_id)
,rideable_type = as.character(rideable_type)
,started_at = as.character(started_at))
q4_2019 <- mutate(q4_2019, ride_id = as.character(ride_id)
,rideable_type = as.character(rideable_type)
, started_at = as.character(started_at))

Then it returned the same error again. Any advice would be greatly appreciated
