where is this option existed in 2020
Ths option no longer exist since a lot of years ago. That was a setting for Windows 95/98, but newest version of Windows doesn't allows that applications do it. As far I remember, this setting still exist under Windows XP but it doesn't make effect, since XP doesn't allows it.
If you want to increase Memory, you should increase the Virtual Memory on Windows (not RAM). By default, Widows start with 16 Mb and set up to 1 Gb,,, that's not enough for current programs. You should set at least 20 or 30 Gb for Virtual Memory. That will give you more stability. And disable that Windows manage Virtual Memory

Where on earth did you get the idea that Windows "starts with 16 MB" and "set up to 1 GB"?
(In both cases here, I am assuming you meant "B" for bytes, not "b" for bits.)
Do you think that "minimum allowed" means that Windows, as you stated, "starts with 16 MB"?
And where do you get the idea that it would "set up to 1 GB"?
As far as I can remember these page file allocations are for swopping temp data from RAM to the hard drive. A very painful thing with mechanical drives and irritating with an SSD.
I haven't touched this setting in years. If this happened after you installed some macros and that caused the issue there are 2 possibilities, 1 there are issues with the macros, 2 your system lacks resources to start with.
IMO this setting may help but most likely will not.
