Windows 10: Dualboot, linux won't start. What to do?

hey-ho i have a dualboot with windows and linux for quite a long time now more exactly was the Ubuntu i thought the 18.04 or the 20.04 i can't say exactly because of the error

Anyway, yesterday it was still working, I used my laptop to work and now this morning after the start came directly this window, I tried to restart it several times but it doesn't help. I get into the windows but not into the linux.

On the picture is a crash report which I would like to read out to solve the problem. Only I do not know how.

Thanks in advance,

Bluetooth and dualboot with Linux

I have a common web-developer setup: dualboot of Linux (Arch) for work and Windows for entertainment. And I have bluetooth headphones (Sennheiser HD1 Wireless), that can bee connected to two devices. But there is a problem.

If I pair my headphones on windows, they are not recognized anymore on the linux. If I "unpair" them on linux and reboot into windows, it's not being recognize on windows anymore (so I have to unpair again and re-find the device again). I have been doing
that for 6 months and it has become .. emm ... mildly infuriating.

It feels like I have each OS using the same bluetooth "device id" but using a different "secret" for connection.

So, I have to options:

• change the device ID in one operating system (same way as MAC addresses for network adapters)
• make sure that both OSes use the same "secret"

Is one of these options available on Windows (what I have a legal 10 Home version ... or non-professional version)? Or should I try to fix this on the Linux side? Are there any tutorials for this you can link me to? Or some google keywords?

Buying second pair of headphones is NOT a good option.
