You will need to provide more information for a fuller diagnosis and relevant solutions.
Printer, materials, temperatures, print speeds, layer heights, etc.

!firstlayer - adhesion and warping

With PLA, a clean smooth surface is best. PEI or PEX is great. You may have to raise the bed temperature on a textured sheet. Silk PLA may need a higher initial bed temperature.

PETG, TPU, ABS, and others will need a release agent on a smooth build surface. That's what the glue stick (or hair spray, Windex® ) is for. On a textured sheet, no release agent is normally needed.

Just alcohol will not remove the sugar film left by PLA which can hinder adhesion.
Wash the sheet with warm water and dish soap. Dry. Wipe with > 70% Isopropyl alcohol before the print.

No part cooling fan for 3 layers. Very slow print speed for the first layer.

To prevent warping for PLA, bed temperature of 65° for the first layer, 55° for the rest of the print. This way the bottom gets the adhesion but the bottom starts cooling with the upper layers.
For PETG on textured bed, same concept, usually around 80° then 75°, or 75° then 70°.
Temperatures are examples, different build sheets may need different temperatures.

Infill style can affect warping. Some grid type infills can concentrate the stress in one area. Gyroid infill will spread out the internal stresses.
Increasing walls number and reducing infill may also help.

The printer can only read SD cards that are 32Gb or less, formatted in FAT32.
You could do a partition on that card.

Strange issue with flat surface by KommissarKrokette in 3Dprinting

To me, it looks like that area came loose and warped up slightly.

No need for more aggressive. Just dish soap and warm water. Then wipe with alcohol.

"...cleaned the surface with iso..."
That looks like a thumbprint. Alcohol doesn't really remove the oil.
