I use Zorin OS 17 (based on ubuntu) on a desktop AMD based system and a framework laptop 16 for about a year now and even before that used an older version of Zorin OS for about 4 years on a shitty lenovo laptop and never had any stability problems. Even the lenovo still runs reliably.
The only problem I've had on the desktop is that the linux driver for an ntfs formatted drive constantly corrupted my data on that drive to the point where some of the data got lost. All other drives are formatted with ext4 and work without any problems. Maybe your problems could be similar?
