Instability of Capture One 22 Pro Build 14.4.0.22 (e2ebf76) on MacBook Pro 15 inch

I am running Capture One 22 Pro Build 14.4.0.22 (e2ebf76) on a MacBook Pro 15 inch. The Mac Book is a Reina Screen Model from Mid 2015 and has a 2.5 ghz Quad Core Intel i7 , 16GB of 1600 MHz DDR Memory and integrated Intel Iris Pro 1536 mb Graphic. The computer is running MacOS Monterey Version 12.6.

I have checked and both Capture One and MacOS are up to date.

Whenever I try use the Heal Tool, the system becomes very unstable. Various things happen, all of which make it impossible to continue to edit an image and I forced to come out of the program and restart. Basically, I no longer have access to the Heal Tool.

The types of instability I experience include:

Screen Freezes , program laggs. Program freezes. Image I an editing diapers and is replaced with lots of fine coloured lines. Latest issue that the picture I am editing goes completely black and the only way to get out this mess is to hit the reset arrow in the task bar and loose all edits and the come out of the program and start again, but making sure not to try and use the Heal Tool.

Anyone experiencing similar or the same issues and if so, have you managed to overcome these issues and if so how?
