Fan goes crazy, alt/tab focus doesn't work, and crashes

The fan of my macbookpro runs like crazy when i open dreamweaver. I already had online adobe help that was very slow and took hours just to change one setting. I already un selected the automatically compilation in css settings..

Also when i use alt/tab to switch 'focus' dreamwever doen's take it.. All other programs do..

Also Dreamweaver is crashing randomly..

OSX 10.15.6 (19G73)

DW 20.2 15263 build

Already did re-install DW 

One big pile of crap.

Please fix!!!

Now it is not usable.. and i pay for it!

Refund request!
