Without sharing a (minimal) reproducible example, it is unlikely that
someone else can help you find out whether this points to a problem in

When I run this, I get the following error:
*Error in CPL_sfc_from_wkt(x) : OGR error*
When I run it on my data, I get the same error.

You may try something along these lines:
# read data.frame with read.csv; here, we create an example by hand:
df = data.frame(
a = 1:3, b = 3:1, geom = c("LINESTRING(0 0, 1 1)",
"LINESTRING(1 1,2
2)", "LINESTRING(5 5,6 6)")
)
library(sf)
sf = st_sf(df, geom = st_as_sfc(df$geom))
sf
