Encryption on SD card. Not recovering data after crashing My SD card on Nokia 5 suddenly stooped being recognized one day and all my apps and data was lost. I switched off the phone and reinserted the card, but no use. Then I took the card for recovery with a data recovery company - Stellar Data Recovery in Gurgaon. They inspected and told me that all they can see on my SD card is garbage and it could be encrypted or its logical drive could have completely been wiped. I had encrypted my phone but I haven't encrypted my card. Any pointers on what should I do next? The data is very precious to me and I need to recover it.

This is a SanDisk SD card 64 Gb, class 10 used with a Nokia 5 with Android 9 version

Update:
Thanks for all the answers people. The data recovery company I gave my disk to were unable to proceed with these steps because I suppose they were not as technical to try these steps. So, they returned my card stating that my card is encrypted and also has physical damage so they can't do anything. That left me heartbroken because this data is important to me.

I am planning to do all these steps myself.


Meanwhile, can I insert another card in my still-unrooted phone, which still has the old corrupted card as an adoptable storage in its settings?  


2.Can this new card be made adoptable? Will doing so make the old card's vold keys disappear from the phone?


Can I make this new card partly adoptable and partly removable through disk partition on Android 9? Will this also affect my old card's vold key?


I just need to know that I will not permanently lose all my old cards vold keys if I insert a new card and make it adoptable as well.

Thanks.
the proper way is give your sdcard + device + screenlock pin to the expert  

the Nokia 5 is listed as exploitable. someone with skills can do:  

on the device itself  


make a full ROM dump of all partitions including encrypted userdata partition and encryption key using the read command in EDL mode  
downgrade the bootloader to make bootchain vulnerable  
flash avb/ dm-verity disabled vbmeta from EDL mode  
flash (unsigned) magisk patched boot/recovery or twrp custom recovery from EDL mode  
get root access to (decrypted) userdata partition  
extract the encryption key of adoptable-storage from /data/misc/vold  


on linux machine  


dump the corrupt sdcard with ddrescue  
decrypt the sdcard dump with extracted key  
recover files with testdisk photorec extundelete binwalk etc
