This is a rare occurrence. Seems your version of Stata has problem running the compiled Mata code. I have re-compiled the function and uploaded to the server. Please take the following steps and see if it can resolve the issue.
1. First update asdocx
asdocx_update
2. restart and see whether the problem is resolved
3. If not then please update Stata to version 15.1 (Since you have Stata 15, the update is free), and check whether it resolves the issue.
4. If the issue is still not resolved, then run the following code and send its log to me.
set trace on
log using "asdocx.smcl"
sysuse auto, clear
asdocx tab foreign rep78, replace
log close
set trace off
It will generate a file with asdocx.smcl in the current directory, please send this file to me.
