Windows Terminal中Powershell的oh-my-posh配置失效，仅显示PS>

问题概述 #

• 新电脑已安装PowerShell v7.4，从配置正常的旧电脑复制了Oh My Posh相关配置，但新终端仅显示默认PS>提示符
• 手动执行初始化命令oh-my-posh --init --shell pwsh --config "C:\dropbox\oh-my-posh\themes\cobalt2.omp.json" | Invoke-Expression后，格式化后的路径会短暂显示，随即恢复为默认PS>
• 已同步旧电脑的Windows Terminal配置，问题仍未解决
