I'm getting the same thing but on 2.25.2. Did anyone solve this?

I am not able to reproduce.
Might depend on the web server or browser you are using.
I recommend to check the web server and PHP log files for errors and warnings.
Check also the browser console for any errors or warnings, try also disabling any browser plugins you might have installed.

There are no errors in the php log files nor in mantis.log. All we get is an iis 400 bad request in the log. The user can export but with different parameters or project. I can use the user's failing parameters and it will work for me. I've tried other users and some can export using the same parameters while others can't. There doesn't seem to be a user pattern except it is reproducible. It doesn't seem to matter if reporter or developer. There are no additional plugins. It is running on Azure vm 2022 with the latest patches.

We found if the user resets the column configuration it works properly.
