It seems that this problem is the same as bug#35363:
https://debbugs.gnu.org/cgi/bugreport.cgi?bug=35363

Unfortunately, preview-latex can't help because the log output from
MiKTeX does not provide, looking at the log you quoted in the previous
message, mandatory information to locate the position in the buffer to
put the generated image.

If the preview-latex is vital for you, please consider to switch from
MiKTeX to TeXLive: https://tug.org/texlive/

If you have to continue to use MiKTeX, then please ask the developer of
MiKTeX not to alter the output format of latex.
