I'm having trouble connecting my STM32 H743ZI-Q device to STM32CubeIDE. I've tried various troubleshooting steps, but the IDE still doesn't recognize the device. Has anyone experienced this issue and found a solution? Any guidance would be appreciated!

Yes! Pulling up Boot0 pin during power on, Solved such situations! Sometimes option bytes "BB" and 'CC' triggerred such situations in IDE, but cube programmer can solve it

Welcome to the forum.

Please provide some more context and details of the device, the issue, and the troubleshooting you've tried, etc - see: How to write your question to maximize your chances to find a solution.

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.

Check exact pinout, the Q / SMPS devices tend to be different too the LDO variants and not drop in replacements / substitutes
