What should I do if I cannot open install.wim? Solving the problem that install.wim cannot be opened when installing Windows from a USB flash drive

Generally speaking, we use the UltraISO tool to open Microsoft Windows ISO files, and use [Start]-[Write Hard Disk Image] from the menu Create a Windows installation boot disk. During the writing process, the USB disk being written is basically formatted into FAT32 format.
