We might have already fixed that in #3541 and it's part of the 4.10.1 release.

There's something weird going on. In the initial issue that @phunkeler created, he indicated he was using 4.10.2 but the stack trace above includes source code that doesn't look like it has the fix applied:
File "Device.cs", line 459, in Device Device.FromJson(JsonElement json)
var processorFrequency = json.GetPropertyOrNull("processor_frequency")?.GetInt32();

The change log for the 4.10.2 release doesn't appear to include that fix either:
https://github.com/getsentry/sentry-dotnet/blob/4.10.2/CHANGELOG.md

PR #3541 that included this fix this was merged 5 on August 24th however the 4.10.2 release was made August 21st.

So I think our change log got broken - that fix is still unreleased.
