Galaxy S10e stuck on boot screen - cannot get into download mode or recovery

I have Galaxy S10e (beyond0lte), which had crDroid 11 installed. I flashed the latest stock firmware, then TWRP 3.7.0.0 patched with Magisk 25.0 using Odin and was able to get into TWRP. In TWRP I installed the crDroid 12 zip. It appeared to succeed, I wiped cache/Dalvik cache as suggested, and rebooted. My phone is now stuck on the boot screen showing > This phone is not running Samsung's official software. (blah blah blah) > > Samsung Galaxy S10e I left it like that for a good half hour just in case. The only thing I can do now is reboot by holding Vol Down + Power. **I cannot get into recovery mode nor download mode**, no matter how many times I try the key combinations (Vol Up/Down + Bixby + Power) - it just goes back to that screen. I was able to do both before installing the crDroid 12 ZIP. Is there anything I can do to recover this phone?
