No Pi hub for experiments but have used powered and unpowered hubs with the occasional problem. Disks left plugged in from power down to power up may not mount. Seems to be problem with the badly written USB 3 standard. USB 3.1 devices do not fail that way.
I have not found the problem with a USB 2 device, like a mouse, or with a USB 2 hub, either powered or unpowered. Sounds like your problem is either the hub not handling USB 3 states when powered or the power supply is providing only a marginal voltage. Test, as mentioned in the previous post, without the power supply.
Then test with a Pi 4 or Pi 5 official power supply.
