Adobe illustrator not working properly on MacBook m1 max

We were working on adobe illustrator(all legal and updated) on our old iMac(2020, i5, 64 gb ram, 4 gb GPU)

perfectly. But we have to work outside of the office so we bought MacBook Pro 16, m1 pro max, 32gb ram, 1 tb ssd version. And additional apple Studio Display, because apple does not allow to iMac to use as a external display. Totally nearly 5.000 USD we paid but MacBook Pro m1 Pro Max not working properly on illustrator. We sold our old iMac retina because we believed macbook pro is very powerful as advertised. This is an unbelievable situation. Now we are looking second hand intel PC, or intel MacBook Pro.

We are drawing on procreate on iPad Pro, then make changes on adobe illustrator. Save as Ai files to Tiff files and we print Tiff files on our printers.

The files we generally work with are 500mb to 1,5gb .Ai format documents. We can easily work with this big files on our old 27 inch iMac Retina. Now when we want to save 500mb .AI files on new MacBook Pro m1 pro max cannot do this, or it takes 3-4 times more than before.

When we want to save as ai files to 300 ppi Tiff documents, MacBook Pro m1 pro max says "out of memory" and can not save it. 250 ppi same, 200 ppi same, 170ppi same... Only we can save documents on 150 ppi.

There is no 3rd party plug-in, no Chorome, no clean my Mac, no 2.ssd to save, no "save on adobe cloud".

We open and close the adobe application every time, working on only 1 documents at the same time.

-We change the Adobe Performance settings to use GPU or CPU but notting change.

-Granted adobe / Illustrator full disk access

-Disabled "Optimize File open and save time on slow networks" in preferences

-Disabled "Save in background" in the Preferences

-We delete all adobe applications and re-install but noting change.
