I (20M) really miss my friend (20F). What should I do if I see her in the upcoming class?

Title. Disclaimer: English is not my native language, and I can't find a better way to frame it. However, I have no romantic intentions / crushes for her. With that, let's start with the context. Long post warning I guess. TLDR at the bottom.

We were friends for about 3 semesters, this current moment is the beginning of the 4th one. We were in the same class (for context I have a larger friend group containing me, her, and some other guys) and we would usually sign up for classes together, although it's common to deviate from everyone a bit and sign up for whatever thing you wanted. That said, me and her usually signed up for the same stuff together. In this current one, we even share TWO out of our THREE classes!

So everything was fine until last Friday. She told me something that she hadn't told anyone else outside her family: that she was dyslexic. Knowing it, and how struggling at this kinda stuff she was (she has balls to go for this field with like a lot of reading and writing, might I say); I decided to help her install OpenDyslexic and it's monofont variant. She was simply overjoyed by it, and even said that I saved her life. And I walked home happy...

Until nearly 20:00 of that day. Apparently she said that she had to block me for some unspecified reason. And I was like: "what the f***" and told me that the next day she would tell me the reasons why. And I was flabbergasted; what did I even DO? OK, at the time installing the font I was kinda headpatting her and stuff, but I thought that's kinda what normal friends do, right? (that or maybe I have zero idea how much affection is too much).

Then came Saturday. No explanation. She did told me a detail that I wasn't the only person blocked. So I was thinking "OK it's fine for her to block me, but should she at least try to explain why AND who are all the other people she blocked?" Once again, no answer until 20:00 of Sunday.

So this time, she finally brought the great reason. Apparently, she wants to favor her (actually romantic) relationship and makes effort for it, except she kinda says something like "really messed up because of me" and "don't be so overthinking about it", which to me seems kinda... weird? Then she said that her romantic partner is somewhat easy to get jealous, and she was (persumably?) intense with them, and she chose to block me (and apparently some other people that she said "She talked a lot too", and I don't know any of them) to "reduce tension". She also said that me and her can be OK IRL, and something like "when you have a girlfriend you'll understand me, most girls are jealous like crazy" which feels... weird (idk I don't really talk to girls, this is IT, girls are rarer than diamond in this field). And with that, I am blocked until now, nearly 23:00 of Thursday without any feedback from her yet.

For some reason, I feel like there's something wrong in her relationship. Like... I could probably list more if you ask, but that's that. Now, apparently the instructor for the Friday class said that class was cancelled, so I had to wait until Saturday to see her again. And it feels weird because we literally spend the entire August as semester break after finals and stuff, so I virtually didn't talk to her at all, but the option to was always there, not like... this. Feels to say that I really miss her non-romantically, just that I want her to be OK and all. But I'm not sure how do I feel about my friendship. It's just that... we did a lot of things together, a lot of memories (like last semester the two of us were in a group project and we scrambled everything and still got a 76%, was fun while it lasted); and stuff like that.

So the class in the incoming Friday is apparently cancelled, what do you think I should do in the morning of Saturday if I see her?

TLDR: friend blocked me last week because of her partner and overall relationship issues, and I miss her and the connection as it was the good old days was. I will see her in the upcoming Saturday, what should I do?

(side note: yes my uni actually teaches on Saturdays).
