Subject: 5.10 RC 7: grub2 out of memory

I just compiled and installed 5.10 RC 7 and got a message from grub2:
"out of memory, press any key to continue" shortly followed by a
kernel panic (see attached screenshot).

The 5.4.0-56-generic kernel from Ubuntu works on my machine fine.

Things I have tried so far:
- setting grub video mode to "console"
- setting grub video resolution to 800x600
- regenerating the initramfs for 5.10 RC 7
- verifying that /boot has free space
- changing boot mode from UEFI to legacy BIOS

I have attached the following:
1.) dmesg ran from using the 5.4 kernel (since I cant boot into 5.10 RC 7)
2.) my 5.10 RC 7 kernel .config
3.) screenshot of kernel panic after "out of memory" grub2 message
4.) my /etc/default/grub

Please let me know if you would like any more information or testing of patches.

Thanks,
Elias
