"The card was used as internal storage" - This means it is encrypted and tied to the decryption key on your device. If your device is already rooted, you Might be able to access the key and use this to access it, it requires Linux and some terminal use, Windows will not be useful for this operation.
If you removed this card while the device was powered up and the card mounted, which it will always be as internal storage, you likely corrupted the drive's file system, and recovery of data from a damaged, encrypted file system is extremely difficult and often requires professional forensic data recovery if the decryption key is available, it's impossible without it, and those services are rather expensive and can be thousands of dollars in some cases.
When a drive is adopted as internal storage, it is reformatted to Linux ext4 file system and encrypted, it is intended to never be removed from the device, ever, unless you go through the process to convert it back to portable storage. The encryption used is very secure, without the decryption key it is generally considered impossible to access the data even if the file system is completely intact and undamaged.
So basically I am saying you're most likely out of luck... The chances of recovery of the data is near zero.
