Try turning off the setting that turns off the headed bed after a few layers.
Otherwise post a pic of your first layer.

My printer keeps the bed heated until the print is finished. Don’t think that’s the problem!

My attempts at printing the large models (see how they are all stringy, the filament is not stuck together as a solid object)
Post a pic of the first layer on the bed. I suspect your z offset is too high and you need to smush it into your bed more.
I have edited the post with a large first layer print. There are many imperfections, what does it mean?

How old is your printer. ?
I had near 2000 print hours and started having first layer problems. I did a lot of troubleshooting and nothing worked.
Ended up being that the heat block needed replaced. Even though it seemed to be functioning. It was causing flow errors or something.
It could also be that the screws around it get loose. That’s actually been most people’s issue but that wasn’t mine.
I replaced the heat block and it fixed it. Here is a link to the thing I’m talking about. Explains to check screws first before considering replacing the heat block.
Hopefully that’s your issue cause that’s easier to do than replacing the heat block.
A poor first layer may not be super noticeable at first. But the problem for me was it got worse over time and did result in prints lifting.
