When updating Sequoia in my case I had a problem because it continually reconnected, it didn't let me work, however on another MAC I tried installing the same operating system and the Citrix worked perfectly.
So I thought that the problem was either an incompatibility with some app or some item that was running in the background; I tried to close all the apps and only run the Citrix but I continued with the same problem, so I compared the items and extensions that were running in the background, and I discovered that on my MACbookpro that was working perfectly the Citrix did not come with any network extension, However, on my MAC it is, so System Settings / General / Startup items and extensions, in the Extensions section I entered Network Extensions and deleted them and the problems were over.
