Adobe Illustratior initialization crash because to much fonts

Hello everyone, I am asking for your solution.
I am using Ai 2020 24.1.2 (64 bit). The problem is that I have over 5000 fonts, when I install Ai the program opens normally and I use it normally, when installing 5000 and more fonts (while Ai is on) I also have no problems using the program. It takes a bit of time to get all those fonts into the program, but it updates very quickly in that regard. The problem occurs when the program turns off and I want to turn it on again, then Ai doesn't open at all, I get the initialization screen and that's it, it freezes, then I have to force turn it off and everything in a circle... Sometimes it asks me to do the test, which I confirm, but it freezes again and doesn't do the test for two days. Is there any solution to this problem? I've checked to see if I have any fonts that are corrupted or something, but there aren't any. I deleted everything from the fontcache, but the file FNTCACHE.DAT cannot be deleted, because when you restart the computer, it comes back again.
I didn't have any problems with these things before and it took me a while to figure out that it was because I removed all other things (configuration and others).
