I think it is related to #1281 (comment)

For me I have to use import dayjs from 'dayjs' in the newest version instead of import * as dayjs from 'dayjs'

@iamkun Could you tell me when you plan to publish the next release? My package is requiring dayjs^1.9.8 and this issue is inflecting my package. If you are not planing to revert in the next 2 days, I will publish a version to lock it down in 1.9
