Slow thinking mode, it gets stuck

[alezhito18]

Description

I have a problem. I'm using Deepseek v4 Pro and v4 Flash for my project, but sometimes it gets stuck on "thinking" and doesn't progress. I can't pause it either; it doesn't work. I have to close OpenCode, reopen it, and re-enter what I was typing. Why is this happening? I'm using the latest version.
