Admin page blank?

I usually update my Grav website with cli. I decided to login to the admin page, and it comes up blank. I ran bin/gpm install admin and re-installed the admin plugin, but it still comes up empty. That also cleared the cache... so what is my next step to get my admin page back? I tried two different browsers (Safari, Firefox) to make sure it wasn't a browser issue. Any help is appreciated.

php version

php -v PHP 8.0.21 (cli) (built: Jul 14 2022 09:52:22) ( NTS )

I should add to this that the web page works fine with no problems. It is only the admin pages that will not load.

I visit mywebsite.com/admin and I get the login. When I put in the login credentials, it goes to a blank page.

I still have an issue. In the logs, I found this:

August 19th at 4:07pm CRITICAL Allowed memory size of 125829120 bytes exhausted (tried to allocate 1298432 bytes)
August 19th at 4:06pm CRITICAL Allowed memory size of 125829120 bytes exhausted (tried to allocate 1351680 bytes)

August 18th at 11:50am CRITICAL Allowed memory size of 125829120 bytes exhausted (tried to allocate 1425408 bytes)

So, why am I running into a memory error? What can I check.
