No starting estimate was successful error with coxme upon data subsetting

I have a large dataset that I subsetted and created a new dataset. I used the following code that works perfectly

require(sjPlot);require(coxme)
tab_model(coxme(Surv(comp2_years, comp2)~FEMALE+(1|TRIAL), data))

But when I used the subsetted datas set using the following code,

www<- subset(data, (data$TRIAL != 5 & data$Sex.standerd.BMI.gpM1F2 >=1))
tab_model(coxme(Surv(comp2_years, comp2)~FEMALE+(1|TRIAL), www))

it gave me the following error:

Error in coxme.fit(X, Y, strats, offset, init, control, weights = weights,  : 
  No starting estimate was successful

This is my new data structure

I saw this post but I could not solve my current problem. Any advice will be greatly appreciated.
