Deleting photos in Photos - High CPU load and crashes of MacOs

Hello,

I am really trying to stay calm, I bought a 16 inch MBP in the beginning of this year and it is getting worse each time I use it, always starting from fresh installs...

So, I imported lots of photo backups, approx. 600 GB of data and now I am trying to remove the duplicates I got. I used two Apps from the Mac App Store which created albums with those duplicates.

When I try to delete those photos by using CMD + A my MBP is under full load for days, I thought myself ok, it has to be this way, fine.

But then photolibraryd crashed. I started all over again, I even put my Library on an external SSD after reading some forum posts about cpu load issues a.s.o.

When I try to delete 50 photos at a time it seems to work, but when I try more than 50 than "Deleting photos is stuck...forever!" I do not know if this has to do with the sqlite db or whatever has been used, but this is not acceptable.

But the best thing is: I got graphic glitches, some weird AMD something something driver issues when coming back to my MBP, today EVERYTHING crashed, I lost bluetooth, Wifi, every process like accountsd on my MBP wanted my password for the keyring a.s.o. - this happened several times in a few minutes leaving the MBP unusable, I could not even open up a Terminal.

Has anyone else encountered such issues?

I am really angry spending so much money on a machine with such issues.
