What's the error if you start the IDE from the terminal? To start the IDE from a terminal, do the followings:

• Open Terminal.app and
• Run /Applications/Arduino\ IDE.app/Contents/MacOS/Arduino\ IDE.

The error still exists, it still takes moren than 5mins to load up.

What do you see in the terminal? Can you share the output?

Hi kittaakos,
I'm also using a Mac running Big Sur. However I don't get a 5-10 minute delay. More like abut 1 minute (subjective, could well be less).
I've attached my terminal log FYI, I don't know if you have many Mac users in your development/test teams.
StartupLog.txt

I've also included a log from my 10 year old MacBook running MacOs Sierra which also does not take 10 minutes.
MacBook startupLog.txt

Both show comments about certain processes being slow, and other warnings.
Hope that helps.

Hello all.

I also have the same issue.
On Windows Version 21H1 (Build 19043.110) the startup dosent finish, the spalsh screen stays forever. Some entries from the menu bar are working for example "Help -> About Arduino IDE", but not all like "File -> New" dosent work.

Looks like it spends a lot of time checking for library and board updates... and retrying in case of error. Seems like these checks need to be more asychnronous.

"root ERROR Error while updating index in attempt 9."

These library checks can be done, and the results of those findings can be stored in json-files, a light database and loaded next time from there if after a quick check it is clear that there has been a change in the libraries. Personally I have been loosing the time of a good holiday waiting for the Arduino IDE coming up in previous version, staring at the screen as if tomorrow does not exist, wondering who in earth makes this to be so slow and is able not to itch its brain to rethink the necessity of all the initialisation checks, and if maybe the outcome of these checks is 99% the same as in other starting up of the IDE. Ideas like caching of results come to mind, databases as stated, or simply an option in the menu for the user to update the Library-Database. It is all a bit like a car starting by itself when you walk to the grocery-store, since maybe you want to use the car for that and then the car needs to be up and running. This costs all wasteful gasoline, or wasteful CPU, HD-time and what not.
Long story short: Needs heavely improved. Also in 1.8.x
