I'm running 64-bit exe

@fxqy Can you please indicate the filesystem that you used when the issue happened?
Also, what is the size of your volume?
I did several tests using portable mode like you and with different filesystems (FAT, NTFS, exFAT) but I was not able to reproduce the issue.
Thank you for your help.

@idrassi I didn't create an encrypted volume with a quick format, and decryption is slow now. I used to use cncrypt, decryption encryption is very fast。I'm using exFAT format, I'll try other formats later

I created a 50G NTFS volume, fast formatting is still particularly slow
Moreover, after the formatted exe is closed, it still occupies the file and cannot be deleted

I'm using 1.25.9, I'm encrypted with aes(twofish), which is a lot faster. Seems to be a problem with the kuznyechik(aes)
