MacBook Pro start up issue, says dead battery when not...

Hi, I've seen this issue in another post from 2017, but it wasn't solved. Hope someone can help 🙏

This is the issue with my MBP (15 inch, 2018, A1990):

1. Mac use - with battery at 95%. Turn off with battery aprox. 70%.
2. Open mac: It says battery is dead, need to charge.
3. Close it, open it again, same thing.
4. Connect it (even to a small power supply, like an iPhone charger) and it starts normally
5. Disconnect it (even before the main user window appears)
6. Everything runs normal, running on battery at 67% approx.

I should mention that step 3 sometimes has worked, as if the fact of closing and opening the lid again makes the mac realize it's not dead.

Heres a screenshot of battery status:

Also, last year after begging to an Apple Care manager (I was suffering this and other issues), he kindly put my mac up to an Apple Care Service and they took it and changed the battery, logic board and Touch ID board. Here's the specs:

I'm a little experienced with computers so I've already tried things like SMC reset and other go-to solutions of this kind, but I haven't found any solution for this issue.

I'm stuck with almost 3000€ worth of Mac, with a battery and logic board newer than the mac itself and I can't take the laptop outside being sure that it will turn on 😅

Any help will be much appreciated.

Thanks!
