I'm aware of this bug as well, where a job box will fail to spawn on a workstation even with all the requirements met.
Luckily, I've been in contact with the dev on his Discord (https://discord.gg/xfumykAd) and he's pretty responsive. He says he's looking into it, but he could always use more data to work with.
If you want to help, I'll write the instructions to submit a bug report here:

Go into Windows Search bar and paste this pathway: %userprofile%\appdata\local\GrimRealms

This will bring you to the file folder that contains the game data. In this folder, you'll find a file named "worlds", open it. Inside worlds should be a list of the worlds you've created. Find the relevant world and copy the whole folder with CTRL + C

Then, create a .zip file somewhere safe and empty(like downloads) and put the world folder into the .zip(CTRL + V)

Finally, join the Discord and go to the #bug-reporting channel. Write a brief description of the bug, and attatch the .zip folder in the Discord message.

Considering it's two of us now who've encountered this job-box workstation game breaking bug, I'm sure Mattias(the dev) will focus handily on patching it soon.

Beyond the job box glitch, I haven't encountered any other truly game breaking bugs, just minor ones. So once he patches the job box bug, the game should be good!

dang I wish I knew earlier. I already deleted those worlds thinking I screwed up creating them. I have been able to get around it somewhat. Biggest thing I see is that when you check if you have the resources, it counts for ALL, even those NOT yet in your storage( like trees just chopped down). I think it wont create the work order until there is enough wood IN storage and not being X hauled to build something else like a door. as for the other bugs I found were order overwrites. if you try to mine a rock/ore and the bottom part of it goes away. the rock/ore falls, so when your people try to mine. the "order" says there is something there, but it is actually 1 tile down. easy fix is to cancel and re apply. I have not figured out work a rounds for the others yet. If I create the bug again Ill do what you listed. thanks for letting me know :)

I still have the same problem... is 2 years after this post. Hopefully is there a fix somewhere :)
