UnicodeDecodeError: 'charmap' codec can't decode byte

[sdv75]

Windows 10 Python 3.11
In the example code

import asyncio
from shardx import ShardX

async def main():
    sdk = ShardX()
    # Engine + Widevine + fingerprint library auto-download from CDN on
    # the first `session`/`launch`/`list_profiles` call (~170 MB once,
    # etag-cached afterward).  No separate install step.

    # Create a persistent profile from a library template (or create_profile()
    # for a random one). Library templates aren't launched directly — this
    # freezes an enriched copy under a unique id you can return to. Do it once.
    profile = sdk.create_profile("win-rtx4060")

    # Launch + drive in one call. Yields a patchright `Browser`.
    async with sdk.session(profile, proxy="socks5://user:pass@host:port") as browser:
        ctx = browser.contexts[0]
        page = await ctx.new_page()
        await page.goto("https://browserleaks.com/quic")
        print(await page.title())

        # Inspect what the SDK resolved before launch:
        sess = browser._shardx
        print(sess.geo)                   # GeoInfo(...) from ip-api / ipapi.co
        print(sess.proxy_udp_ms,          # UDP RTT in ms or None
              sess.quic_enabled,          # bool
              sess.webrtc_mode)           # "auto" | "tcp_only" | "block"
    # browser + udd shut down cleanly on exit

asyncio.run(main())

I get error

I suggests solving this problem by replacing in .venv\Lib\site-packages\shardx\profile.py line
cfg = json.loads(p.read_text())
to
cfg = json.loads(p.read_text(encoding="utf-8"))
