Got a laptop here that only supports opengl 4.3. Doesn't seem to have vulkan support either, or opengles - I just get severe text corruption and hud corruption. I know you can run on 3.3, I just can't find out how to force it.

Use the command line switch '-glversion 3'.

If you have OpenGL 4.3 then you also have OpenGLES as the latter is a subset of OpenGL.
More details would be needed - you know the drill.

Also note that GL 3.3 mostly runs the same code as GL 4.3, the main difference being that it cannot persistently map the buffer and has to lock/unlock it before drawing anything.

What kind of graphics hardware do you have? Broken drivers like this are quite rare and normally an update should be possible.
Intel 5500. The laptop would be from about 2015 I think? Which makes it unusual that it would have this issue - 3000 and below, sure, not expected to run the port.

Gles didn't work either, here's my log with the -glversion switch:
Gles log:
And since screenshots didn't seem to work, and I can't see the menu in order to bind it to a key, some phone screenshots of what the console and the map look like:

How about setting a higher resolution than 320x200? Maybe that driver doesn't support going so low.

Tried to via command line and the video mode menu (What I could see of it at least), and it either didn't work or caused the same issue. Log from using -width 1280 and -height 720 (After the gl and log file arguments/switches):

What if you start with a fresh config?

As in deleting the ini file? Seems to make no difference.
