I'm developing a project in Delphi Rio 10.3 Community and it currently has 24 units. This particular form I'm having problems with contains 28 frames of the same type, each containing a TChart component with a few buttons and checkboxes (print chart, show/hide series/labels, etc.). Everything was fine until about 20-25 frames/charts, but yesterday I added a couple more till I reached 28. No errors whatsoever at design nor run-time, so I closed Delphi happily at the end of the day.
Problem started next time I started Delphi. The exact error I'm getting when I simply open my project is "Error creating form: Out of memory." After acknowledging the error the project still opens fine, except for this particular DFM file with 28 frames/charts. I can still compile and run the project without any issues, but I can't visualize the form in the IDE in order to develop it further.
I understand I reached some kind of limitation, although the project/form is not huge. I have an i7 with 32GB memory, Windows shows I have 26GB free, so I think that's plenty.
I didn't find any reference to this exact error message on the web, but some similar compiler error, which is not my case:
http://docwiki.embarcadero.com/RADStudio/Rio/en/F2046_Out_of_memory_(Delphi)
However, I did try the workaround with increasing the swap file size in Windows, but no luck.
I also installed the latest IDE Fix Pack 6.4.2 from Andy, again no success:

DFM file has around 3000 lines, so pasting only one of the 28 frames/charts in it:

My guess right now is that the problem started when I passed about 25 frames/charts, if there's some kind of limitation there. My problem is that I can't break down this form into smaller ones, as the charts I'm presenting only make sense when shown together (they are parts of a larger production flow). And I barely started, I was planning on having 35-40 graphs.
Considering my project works OK at run-time, one solution would be to add the frames/charts at run-time, but that kinda defeats the purpose of using a RAD.
Any help appreciated, thanks.
