Just wanted to add that I also have the same issue. For me there is one slight difference though - it happens 3 times each time instead of 2 times. In other words, all input locks up for about 2-3 seconds, then I regain control for about 1 second, lock up again for 2-3 seconds, get it again for 1 second and finally, lockup again for 2-3 seconds. Sounds like the same as you but it happens in 3s for me.
Since the season 1 patch, it has happened much less than before the patch. Previously it would happen at least 3 or 4 times each map, but with the new patch, I find I can play for 3 hours and it only happens about 3-4 times. It still drives me crazy, but a little less so I suppose. Like you, it doesn't happen on other games I play (Sniper Elite 5, Rainbow Six Siege) and my system is no slouch (i9-12900K, EVGA 3080 Ti). My Windows 11 OS and the game are both on Gen 4 M.2 SSDs (the OS and game are on separate drives) so I'm not sure what could be causing it.
I am hopeful that the future games will ditch the Frostbite engine and use something else - maybe that will fix it.
