HOW CAN I FIX THIS BUGS

Please try to reset the preferences of Photoshop using the steps described here: 

Preferences in Photoshop (adobe.com) 

Please backup your settings before resetting the preferences. You can check: 

Migrate presets, actions, and settings (adobe.com) 

Another try it to turning on the option »Deactivate Native Canvas« (Photoshop > Preferences > Technology Previews) and restarting Photoshop. 

If the issue persists, try to disable the option to "Use Graphics Procesor" from Photoshop by going to Preferences, then Performance. Once done, quit & relaunch Photoshop to check if that helps. 

If you're unable to access Preferences and PhotoShop crashes before that, please go to the location C:\Program Files\Adobe\Adobe Photoshop 2021. Then rename the Sniffer.exe to Old.Sniffer.exe and try launching Photohsop again.
