I don't think it is possible or economically viable for ByteDance to sell TikTok under the terms set out, even if they wanted. Because of the shared code base with Douyin and the bill's requirements on severing ties between the two.
The likely outcome is that TikTok will stop operating in the US and continue in Europe and other places plus Douyin will continue in China.
