[BUG] Summarize Breaks and Other Mata Load Error

[thodurfee]

Bug report

OS : Windows 11
Stata Version : 14.2, SE, 64bit version
Both ftools and reghdfe are updated as of 10/11/2023

Over the summer, I ran a series of regressions using reghdfe with the ,summarize option. This code ran fine.
Now in the fall (I believe after the ftools update) when I run the same code, I get the following error:

   _assert_abort():  3498  assertion is false
              assert_msg():     -  function returned error
  add_undocumented_options():     -  function returned error
                   <istmt>:     -  function returned error

I have tried reinstalling ftools and reghdfe, restarting my computer, and updating stata, none of which have worked. I am told many who face this issue have space issues on their hard drive, but I have over 25 GB open on my operating system drive, and the dta file is just under 100 MB.

When I omit the summarize option, the code sometimes runs, but sometimes still gives an error.
I tried using older versions of reghdfe, and using smaller poolsizes.

Documentation says that this functionality is a part of sumhdfe, does that mean this feature has been discontinued for reghdfe?

Below is the code I get from trace mode, although the data set is based on a special project where I am replicating someone else's code, so I cannot supply the dta:
