I have a las catalog data that doesn’t have coordinate system , without coordinate system i can easily compute pixel metrics but when i assign the coordinate it doesn’t work,i need to have x and y for the outcome table ,can you help me with the problem

normalized1987<-readLAScatalog("normalized1987")
st_crs(normalized1987)<-4326
heigh<-pixel_metrics(normalized1987,func = .stdmetrics_z,res = 30)

i tried las check and i got this error
Checking overlapping tiles…Error in wk_handle.wk_wkb(wkb, s2_geography_writer(oriented = oriented, :
Loop 0 is not valid: Edge 0 crosses edge 2
In addition: Warning messages:
1: In st_is_longlat(x) :
bounding box has potentially an invalid value range for longlat data
2: In st_is_longlat(x) :
bounding box has potentially an invalid value range for longlat data
but also filter duplicate doesnt work
