StarBrowser did a restore pointing to the downloaded "ASIAIR-Pro-OS-For-EQ6R pro.rar" file
See if you can uncompress the .rar first (Roshal Archive, named after its developer). Then point ApplePie Baker to the uncompressed file.
You may need to download "The Unarchiver" program (search Google), to uncompress the RAR file.
Even when making an archive, I have found ApplePie Baker to not be reliable making a compressed file. But it is quite reliable with saving and restoring .img (disk image) files.
If that still does not work, don't use ApplePie Baker v2. In the download page (well hidden way down their download page) there should be a 64 bit version of Apple Pie Baker v1. That version (64 bit version of v1) seems the most reliable for me (including through Rosetta II on the Apple Silicon MacBookPro and Mac Mini machines). You just have to give the v1 permission to access the drive every time you run it (your Mac's user name, password).
After you have successfully burned a microSD card, there should be 4 volumes on the card, but only one volume, called BOOT, is visible by the standard macOS. The other three are in Linux ext4 format. You can still read their contents on a Mac, but you need a kernel extension like the extFS program from Paragon Software. But you should not need to read those Linux volumes. Looking for the BOOT volume is a good sanity check, though. Be sure to eject the mounted volume softly before ejecting the microSD card from your Mac.
By the way, I was assured by email earlier this evening that the next version of ASIAIR will include the Prolific driver. But I was not told when the beta of the next version would be coming out.
