Ventoy upgrade

[cscs]

Hi, Ventoy new version files come out, but how to upgrade stick?

Seem upgrade option is broken or not available for 1.0.21 release
The Upgrade box is grey off.

My original version is 1.0.20.
Confirm upgrade option is not available when I try 1.0.21 as upgrade option is grey off.

The disk partition table may be changed since ventoy 1.0.20 installed. You can give the log.txt for debug.


Sorry, has did this:
1. Copy all program/ISO to a spare disk.
2. Use 1.0.21 (do not have upgrade option), it format the whole USB disk.
3. Copy back those files backup in "1" and it works.
But is kind of time consuming.

Update:
After USB stick has upgraded to 1.0.21, running 1.0.21 again,
Ventoy can now show Ventoy in package 1.0.21 and Ventory in Device 1.0.21
Previously, it show Ventoy in package 1.0.20 and Ventoy in device is blank even the program do detect my USB device correctly.
