Go 5200 restarts automatically every few minutes

I have the same problem with the comment that it only does that when I connect it to my iPhone 11's Personal Hotspot
I normally always have this while driving to get up to date traffic info.
Unfortunately that is no longer possible and I have to drive offline, which I think is a loss.
This has come after the last update of the map of Europe 2/3 weeks ago.
Does anyone know a solution?
The card tray did not load properly at the time, would that have created the problem?

I have found disabling MyDrive Sync seems to have solved this problem, but could @Lochfrass explain why and what are the consequences of doing this in the longer term

I had a problem that my Go Premium continually freezes then restarts over and over. I found that if i turn the My Drive syncing OFF on the device then it sorts out the problem. But it means I cannot connect to the My Drive app on my phone!!

My GO 5200 restarted twice during navigation. But the scenario was a little different than described above.
The first time was in sunny morning, with the Europe Map v.10.70, and the second time was, some two weeks ago, during the sunny noon, with the Europe Map v.10.75. The second time my classic phone was paired with my TT via Blue Tooth (only for the hands free telephone conversation purpose).
Both times, after restart (only one restart), the voice unit/function has stopped. The route navigation was working OK, but there were not even audible warnings, e.g. about speed cameras, although they were indicated on the screen.
. Also the voice control didn't work, despite it was working before restart.
Because of the sunny condition, I thing that the restart with the following voice functions shut-down was related to overheating (this kind of restart has never happened during night travel).
I have the MyDrive Syncing turned ON. Will try to switch it off. But I think, that it might be related also to another setting: I have turned ON the settings: "Ask me so I can choose" (in "Route Planning" -> "When a faster route is available"), and "Use voice to accept an alternative route" in "Voice Control".
In both cases, before my device has restarted, there the traffic jam was expected somewhere far ahead of me (that's what I have heard from my TT), and there might be that the alternative (faster) route was found (prior to the restart), but my device did not ask me (by voice) about confirmation of the alternate route.
Another thing that supports the idea, that these restarts were caused by the device overheating, is that, after I have reached the target, I had to wait some half of an hour, with the device placed already in the cool interior of the house, before the device was able to boot properly.
