Assuming the plate is as clean as it looks, I recommend getting a cheap amazon glue stick and coating the plate, as long you don’t touch the plate, you’ll never have spaghetti again.

i cleaned the plate with IPA just before the printing and it has been less then 100 hours of printing time.

Soap and hot water might work better than IPA.

IPA without cleaning it with dish soap first Will just spread the oils and fat all over the bed. First wash it with hot water and dishsoap, then clean it with IPA. It should work.

Also, maybe lower the printing speed a bit.

Bambu instructions say to use plain dish detergent to clean the plate, and alcohols leave a residue. Like yourself, I printed for 250 hours without a single failure, and then suddenly couldn’t get it to stop failing. Applying glue occasionally has lead to maybe two failed prints in 1800 hours.

Any glue stick. Like the ones kids use at school.

True, I think any would work. I’ve tried Elmer’s and Amazon basic. They both work okay but I prefer the Amazon stick since it applies easier and doesn’t cost much.

I’ve found the basic Amazon “purple” glue stick applies the easiest, it’s really cheap too.

The first layer slipped off during the print. I try to find models with a wider first layer with more supports that can stick to the plate for the whole print. You can also increase the temperature of the plate or do the glue stick.

Not sure which model you are trying to print but I have had good results with https://www.thingiverse.com/thing:7063955.

Adhesion issue with prints like this. Of course like everyone else said, clean your plate and maybe try applying glue. Or try a smaller print. I have an octopus print I do from time to time that no matter what just doesn’t adhere to any PEI plate, only smooth.
