Build ID: c5fb19a
Tested on a rapsberry pi 4, another user reporrted having the same error.

Once the wallet(s) fails to create, you can't attempt to recreate them because the file already exists:

Only way to attempt again is to delete the files.
I encountered the same problem until I updated to a 64 bit os https://github.com/decred/dcrdex/issues/2698
Probably the binaries were build for 32 bit pi and there is something there.
Raspberry Pi 4 is a quad core Cortex-A72 (ARM v8) 64-bit SoC, so I would definitely expect that you'd need/want a 64-bit OS and arm64 bins.
Caused by wrong binary architecture. Now being built correctly with 64 bit arm... I think
