Logic 11.1.1 issues in SONOMA

I recently update my MacOs to install the Logic upgrade but i'm having mainly this 2 problems:

• I cannot see anymore my recent project , also after opening that nothing is showed , or better , is showed the position but no text inside and if you try to click on this empty spaces logic say "The document “(null)” could not be opened. The file doesn’t exist."
• Secondo problem more important.... when you try to load some of the sample sound logic start to "Load" something and the multi color circle start to run for 2 -3 minutes also just to change a machine sample sound.

Someone can help ?

i cannot upgrade to Sequoia because most of the audio plugins won't work there and i need to work wiht my mac and my logic....
