Spinning wheel and slow performance on Mac Pro

For quite a while now while I am trying to work on a HTML project on  Dreamweaver 21.3 15593Build on my 2019 Mac Pro (2.5GHZ 8-Core Intel Xeon and 32GB of RAM) with Mac OS 13.1 I am experiencing a significant lag in the program and constantly getting the rainbow wheel.

I opened 5 pages to paste some new lines (each page has about 500 lines, not something too big) it took several minutes to even open the pages. Then when I navigate from page to page I am getting the spinning wheel every time. About 5 seconds from one tab to another.

I did a test, added one new line in the code and it took 10 seconds to save it and 20-25 to exit the program.

It will take for ever to make the change to the whole project…

On the other hand on my M1 Pro Macbook Pro I opened 7 pages instantly and worked without any problem and no delay.

Any help would be extremely helpful.
