After upgrade, startup apps were altered again. PATH variables were unchanged this time.
I forgot to mention earlier that the PATH variables did, in fact, change after another restart or full shutdown. The last entry was also truncated (yarn path), but the missing entries (winget/code) were in the middle the last time I reentered them so I don't know how this is possible. Fully missing winget and code again only, as far as I know. Checked character size of PATH and it is 2333 characters. This has happened the last few builds.
