cant delete or create any logical partitions. HELP

I tried fastboot delete-logical-partition product_a (remote: 'Failed to write partition table') and thats because i don't have a product_a partition.

Fastboot erase product_a
Erasing 'product_a'
FAILED (remote: 'Partition doesn't exist')

but then if i try creating a logical partition

fastboot create-logical-partition product_a 1
Creating 'product_a'
FAILED (remote: 'Partition already exists')

like i said its the same on all other partitions = system,odm,... what am i doing wrong? The phone i am trying to repair: **OnePlus Nord CE 3 Lite 5G CPH2467** (i got the system and all other images from the oxygen updater app)
